VM & Container Management

Quick Actions

  • Start, stop, restart, shutdown (ACPI), force stop
  • Suspend and resume
  • Clone (full and linked clones)
  • Delete with confirmation
  • Bulk actions on multiple VMs/CTs

Bulk actions

Available from PegaProx 1.3

Select several guests (Bulk select) in any layout and run start, shut down, stop, reboot, snapshot or tags on all of them. Each guest is checked against your permissions on its own, and the result is shown per guest, so one refused guest does not stop the others.

On a node, you can start, stop or migrate all its guests at once.

Bulk migration runs on the server: one guest at a time, a few at once or all at once. It follows each guest, can be cancelled, and keeps running and reporting when you reload the page.

App containers from OCI images

Available from PegaProx 1.3, Proxmox VE 9.1 or newer

Under App Containers, a container can be created from an OCI image (Docker Hub or another registry): pick one from the small catalog or enter any image by its reference (registry/name:tag). The node pulls the image onto the chosen image storage, where it is reused for the next container from it, and creates the container with the root disk, memory, network and environment you set.

Proxmox VE treats application containers as a technology preview; try them before you rely on them. Only nodes running Proxmox VE 9.1 or newer are offered. Creating them needs the permission to create guests on a cluster where you are not limited to single pools or guests.

VM Configuration

Full VM configuration editing directly from PegaProx:

  • CPU: cores, sockets, type, NUMA
  • Memory: RAM, ballooning, minimum memory
  • Disks: add, resize, detach, change bus type
  • Network: add/edit NICs, VLAN tags, bridges, firewall
  • Boot order, EFI disk, Secure Boot, TPM
  • Cloud-Init configuration
  • PCI/USB passthrough
  • CD/DVD ISO management

Snapshots

  • Create, restore, and delete snapshots
  • Snapshot tree visualization
  • Efficient LVM Snapshots: Space-efficient snapshots for VMs on shared/LVM storage (Proxmox normally does not support this)
  • Bulk snapshot deletion across multiple VMs

Console Access

  • noVNC: Browser-based VNC console for QEMU VMs
  • xterm.js: Browser-based SSH terminal for LXC containers and nodes
  • SPICE: Downloadable virt-viewer .vv for audio, USB and multi-monitor sessions
  • Own window: The header's pop-out button opens the console in a separate browser window, so several guests can be watched side by side. The link is a normal URL you can bookmark or share - it lands on the login screen first if you are not signed in, and the same permissions apply as everywhere else.
  • WebSocket proxy handles authentication and connection tunneling

Affinity Rules

  • Affinity: Keep specified VMs together on the same host
  • Anti-Affinity: Keep specified VMs on separate hosts
  • Works with both QEMU VMs and LXC containers
  • Enforced during live migration and load balancing

Online Disk Resize

Expand VM disks while the VM is running. Guest OS detects the change automatically on Linux 4.x+ and Windows Server 2016+. Only growing is supported online - shrinking requires VM to be powered off.

Hot-Plug Devices

Add Disks

Attach new disks to any SCSI or VirtIO slot while running. All storage backends supported (local, NFS, Ceph, ZFS).

Remove Disks

Detach disks from a running VM. Warning shown if disk appears mounted inside the guest.

Modify NICs

Change bridge assignment, VLAN tag, model (VirtIO/e1000), and rate limiting on the fly.

CPU Affinity

Pin vCPUs to specific physical cores for latency-sensitive workloads. Example: affinity 4-7 pins vCPU 0-3 to physical cores 4, 5, 6, 7. Reduces cache misses and jitter.

VM Tags & Favorites

Tags

Add colored badges to VMs for organization (e.g. "production", "dev", "database"). Filter by tags in sidebar or global search.

Favorites

Star VMs to pin them to the top of your list. Per-user, persistent across sessions. Keyboard shortcut: F.

Global Search

Press Ctrl+K to search VM names, VMIDs, IPs, tags, and nodes across all clusters. Results filtered by RBAC permissions.

Guest Agent Integration

Install the QEMU Guest Agent for enhanced visibility and control:

Feature Without Agent With Agent
IP Address Display Not available All interfaces shown in real time
Disk Usage Not available Per-filesystem usage with mount points
OS Information Basic (from config) Full OS name, kernel, hostname
Graceful Shutdown ACPI signal only Clean OS-level shutdown
Snapshot Consistency Crash-consistent Application-consistent (filesystem freeze/thaw)

bash

# Debian/Ubuntu
sudo apt install -y qemu-guest-agent && sudo systemctl enable --now qemu-guest-agent

# RHEL/CentOS
sudo yum install -y qemu-guest-agent && sudo systemctl enable --now qemu-guest-agent

Extra CPU Flags & LXC detail info

A tri-state toggle panel in the VM Hardware tab exposes fine-grained control over CPU feature flags. Each flag cycles through three states:

  • default - leave the flag unset
  • +enabled - force the flag on
  • −disabled - force the flag off

The selected state is spliced into the VM's cpu= string. The panel covers the standard Proxmox flag set:

pcid, spec-ctrl, ssbd, ibpb, virt-ssbd, amd-ssbd, amd-no-ssb, pdpe1gb, hv-tlbflush, hv-evmcs, aes, md-clear

Warning

Changing a flag requires a VM restart to take effect.

Note

For nested virtualization, setting the CPU type to host already passes vmx/svm through. The discrete flags above are for finer control.

LXC detail info

LXC containers now show their OS type and IP address in the VM detail views.

Disk Operations

All VM-scoped endpoints take the form /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/... where vm_type is qemu or lxc.

Method Endpoint Description
PUT /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/resize Resize disk (expand only)
POST /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/disks Attach new virtual disk
DELETE /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/disks/{disk_id} Detach and delete disk
PUT /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/move-disk/{disk_id} Move disk to different storage

Network Operations

Method Endpoint Description
POST /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/networks Add NIC
PUT /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/networks/{net_id} Modify NIC
DELETE /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/networks/{net_id} Remove NIC
PUT /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/networks/{net_id}/link Toggle link state

Passthrough Devices

PCI Passthrough

GPUs, NICs, storage controllers. Requires IOMMU on host.

USB Passthrough

Individual devices or full controller. For dongles, security keys.

Resource mappings (from 1.3): PCI and USB devices can be attached through the cluster's resource mappings instead of a raw device address. Mappings also work on clusters connected with an API token. Attaching a raw device needs a root@pam connection (a Proxmox rule), and from 1.3 only an operator who is not limited to single pools or guests on that cluster may do it.

Serial Ports

Socket or pty types for OOB management or legacy apps.

Method Endpoint Description
GET /api/clusters/{id}/nodes/{node}/hardware/pci List available PCI devices
GET /api/clusters/{id}/nodes/{node}/hardware/usb List available USB devices
POST /api/clusters/{id}/vms/{node}/qemu/{vmid}/passthrough/pci Add PCI passthrough
POST /api/clusters/{id}/vms/{node}/qemu/{vmid}/passthrough/usb Add USB passthrough

Container features

From 1.3, a container's features (nesting, keyctl, fuse, mknod, NFS and CIFS mounts) can be changed after it was created, in the container's settings. Root-only flags need a whole-cluster operator.

VirtIO RNG

From 1.3, the VM hardware settings have a VirtIO RNG section: it gives the guest entropy from the host, so it does not wait for randomness while booting. Choose the source (/dev/urandom, /dev/random or /dev/hwrng), the limit in bytes per period and the period; PegaProx checks the values against what QEMU accepts before they reach Proxmox. /dev/hwrng needs a hardware RNG on every node the VM may run on. A running VM picks the change up after a restart.

Virtiofs and directory mappings

From 1.3, a host directory can be shared with VMs through virtiofs:

  1. Create a directory mapping in the cluster's datacenter settings: a name and, per node, the absolute path of the directory. Creating, changing and deleting mappings needs cluster.config and an operator who is not limited to pools or guests.
  2. In the VM's hardware settings, add a virtiofs share that uses the mapping, with its cache and ACL options.

The guest needs the virtiofs driver; Windows needs WinFsp and the virtio-win drivers. A VM with a virtiofs share cannot be live-migrated; the migrate dialog says so. Users limited to pools or single guests cannot give a VM a directory it does not already share.

Guest file read

Reading a file inside a VM through the guest agent needs the vm.config permission from 1.3 (it used to need only vm.view), because the agent reads as root inside the guest.

Per-VM Firewall

Each VM can have its own firewall policy independent of datacenter rules.

Method Endpoint Description
GET /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/firewall/rules List firewall rules
POST /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/firewall/rules Create rule
GET /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/firewall/aliases List aliases
GET /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/firewall/ipsets List IP sets
GET /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/firewall/options Firewall options
GET /api/clusters/{id}/vms/{node}/{vm_type}/{vmid}/firewall/log Firewall log

Efficient LVM Snapshots

Thin-provisioned LVM snapshots with instant creation and minimal overhead. Separate from Proxmox built-in snapshots.

Method Endpoint Description
GET /api/clusters/{id}/vms/{vmid}/efficient-snapshots List efficient snapshots
POST /api/clusters/{id}/vms/{vmid}/efficient-snapshots Create LVM snapshot
DELETE /api/clusters/{id}/vms/{vmid}/efficient-snapshots/{snap_id} Delete snapshot
PUT /api/clusters/{id}/vms/{vmid}/efficient-snapshots/{snap_id} Rollback to snapshot
GET /api/clusters/{id}/vms/{vmid}/snapshots/check-capability Check LVM snapshot support

Press Ctrl+K or / to search across all clusters. Indexes: VM names, VMIDs, IPs (from guest agent), tags, node names. Results grouped by cluster, filtered by RBAC permissions.

From 1.3 the search also finds guests by MAC address (separators and case do not matter), by IP addresses from their configuration and by text in their notes, and shows which field matched. Prefix filters narrow a search, for example mac:bc:24:11, ip:192.168, notes:backup, tag:web, node:pve1 or status:running.

Favorites

Star VMs via the star icon or F key. Per-user, persistent, pinned to top of VM list. From 1.3 favorites are stored on the server again and show as a Favorites group at the top of the sidebar in Modern and Corporate, with the usual right-click menu.

VM Tags

Custom colored badges for organization. Filter in sidebar or global search. Shared across all users with vm.view.

Method Endpoint Description
GET /api/clusters/{id}/tags List tags
POST /api/clusters/{id}/tags Create tag
DELETE /api/clusters/{id}/tags/{tag} Delete tag
GET /api/user/favorites List favorites
POST /api/user/favorites Add favorite
