Proxmox Virtual Environment

Set up

  • My NVMe SSD was not detected. It turns out I need to choose ACHI instead of RAID in SATA Operation under System Configuration in BIOS. See AHCI VS RAID: Which One Should I Choose for Better Performance?.
  • Proxmox VE 7 Initial Installation Checklist. 2021
    • To access it, use https://IP:8006
    • Username is 'root'.
    • Change to pve-no-subscription Repo. We need to modify package sources before we run apt update and apt dist-upgrade
  • My initial setup (disk storage is 240GB). However in web page, the 'Disks' tab will show 240GB for /dev/sda and /dev/sda3 (LVM) shows 93% of usage. 
    root@pve:~# df -h

    I don't have a separate disk for storing ISOs. I use the local disk. The iso files are saved in /var/lib/vz/template/iso directory. The bridge network works so I can ssh to the new virtual machine (after install openssh-server).

  • Proxmox Beginner Tutorial: How to set up your first virtual machine on a secondary hard disk
    • You need at least 2 physical drives; one for proxmox and the other for virtual machines.
  • Trying out Proxmox VE, an open-source virtualization platform 2021

Windows VM

  • How to Unlock a Proxmox VM. Then reboot pve.
  • For Windows installation, if we are dropped at the EFI shell, we can use reset -s to shut down the system.
  • Windows VirtIO Drivers & Creating Windows virtual machines using virtIO drivers from fedoraproject.org
  • (Videos) Launching a Windows VM in Proxmox (Win10), Virtualize Windows 10 with Proxmox VE (Win10)
  • In OS tab, be sure to choose the right Guest OS Version; if we choose (10/2016/2019), we will select 2019 in the driver folder locations OR if choose (11/2022), we will select the corresponding driver folders. This affects the later steps when we select the drivers to install.
  • There are 3 drivers we shall install.
    • vioscsi\win10\amd64\vioscsi.inf (we need it in order to see the virtual disk)
    • NetKVM\w10\amd64\netkvm.inf (in order to get network working, this can be installed later from Windows Device Manager)
    • Balloon\win10\amd64\balloon.inf (memory balloon driver, this can be installed later)
    • Guest agent (Qemu-guest-agent). Make sure we have installed all missing drivers from Device Manager. We can go to virtual machine Summary tab to check if the IPs shows the Windows IP.
  • Change network to use a static IP.
  • Enable RDP.
  • For Audio, we need to add it to the hardware list (driver=spice is OK). PS: audio works when I tested using the Microsoft Remote Desktop app on mac. It does not work when I use Remmina app from Ubuntu initially but if I change the sound setting (from "Off" to "Local" in the "Advanced" tab) it works.
  • Windows 11. We can still use 10/2016/2019 for the Version selection. When I check the Task Manager (Windows 11 Pro, Version 21H2, OS build 22000.675), it shows 1.8/4GB was used and 101 out of 127GB is free.
    • OS: version 10/2016/2019
    • System: BIOS: OVMF (UEFI). Machine - q35. Add TPM. Qemu Agent. SCSI: VirtIO SCCI
    • HD: Bus-VirtIO Block. Disk size >=32
    • CPU: Cores >=2. Type - Host
    • Memory
    • Network: VirtIO
    • After finish, adding CD/DVD - VirtIO iso
    • Install: Browse VirtIO disk. AMD - win10. Next, browse NetKVM - win10.
    • After reboot. Continue to answer questions. Reboot
    • File manager. VirtIO disk. Run virtio-win-gt-x64.exe.
    • Right click on Start. Device Manager. All clean.
  • Windows 11 VM / Office 2019 install error 0-2054

My Proxmox Home Server Walk-Through

Display, copy-and-paste

  • For Windows OS, we can use the default (noVNC)
  • For Linux OS, SPICE is better. Screen can be scaled as we want. Copy and paste still does not work after I installed spice-vdagent. virt-manager Spice copy paste doesn't work. But the copy-paste function works in Debian VM launched by Virtual Machine Manager (actually the menu bar are different. One is called 'Remote Viewer'/remote-viewer and the other embedded viewer from /usr/bin/qemu-system-x86_64 is called 'QEMU/KVM').
    • (Debian11 and antiX VMs) When I use "ps -ef | grep spice", I got /usr/sbin/spice-vdagentd & /usr/bin/spice-vdagent as shown in the screenshot here for the VM launched by QEMU/KVM. But I did not see /usr/bin/spice-vdagent in the VM launched by Proxmox.
    • B/C a hint from above, I found a solution here. After I run /usr/bin/spice-vdagent , copy-and-paste works!
    • In summary, 1) sudo apt install vdagent 2) /usr/bin/spice-vdagent
    • (Fedora 35). Copy-and-paste works out of box (vdagentd & vdagent are automatically running in the background). Maybe it's because Fedora is a Red Hat based Linux OS.
    • How to add spice-vdagent to VirtIO VM?

Sound/audio and SPICE

Remote Desktop through browser

Qemu-guest-agent

https://pve.proxmox.com/wiki/Qemu-guest-agent

can't shutdown a VM

Use the command qm unlock XXX 

qm stop XXX
# can't lock file '/var/lock/qemu-server/lock-996.conf' - got timeout

qm unlock XXX
qm stop XXX

Now we can go back to proxmox GUI to remove the vm.

But if the "qm unlock" does not work, we can use the kill command. See Proxmox can’t stop VM – How we fix it! 

ps aux | grep "/usr/bin/kvm -id VMID"
kill -9 PID  # VM will stop

Errors and solutions

Removing ProxMox Subscription Notice

Network

Ethernet port

How many Ethernet ports do I need on my Proxmox?

LXC

Pi hole

Installing Pi-Hole inside a Proxmox LXC Container. 2GB disk, 1 CPU core, and 256MB of memory. The memory usage is pretty flat around 53MB according to Proxmox gui). I am using Debian 11 template. 

apt update
apt upgrade
nano /etc/sysctl.conf # disable IPv6 
reboot
apt install curl
curl -sSL https://install.pi-hole.net | bash
pihole -a -p # change to a simpler password

SMART and wearout

I saw the wearout is 99% on my host disk (240GB Kingston SSD). I cannot delete a VM. If I use the command "qm destroy XXX", it shows "Unable to create output file '/var/log/pve/tasks/1/UPID:pvv....:qmdestroy:108:root@pam:' - Read-only file system". The host disk uses only 37% of storage on root partition. The solution: reboot Proxmox.

Backup and restore VM

  • Backup and Restore from proxmox wiki. How to Backup Proxmox? Proxmox Backup and Recovery Methods.
  • How to backup and transfer a Proxmox VM to another Proxmox Node
    • Backup file has a timestamp on the filename and it is saved to /var/lib/vz/dump if it is saved in local (pve) or /mnt/pve/vm1/dump if it is saved on my vm1 storage.
    • The backup file can be seen on the GUI under $STORAGE (pve) -> Backups where $STORAGE is the storage name (e.g. local). From there, it has a 'Restore' button where we can restore it with an option to enter a new VM ID.
    • If the backup file is saved in local (pve), the backup file can also be seen under the VM|Backup menu.
    • The backup VM has a filename vzdump-qemu-$ID-$Date-$Time.vma.zst (compression by default). If we select the file, we can click the 'Restore' button to restore the VM.
    • After restoring, the new VM has a new ID but the VM name is still the same as the original one (so we can only use the ID to distinguish the VMs). Therefore, if we use the static IP in a VM, it is better to shut down the old one before we Start the new VM.
    • If we remove/delete the restored VM, the backup file is not affected (not deleted).
    • It seems backup + restore = clone.
    • If we back up a container, the backup file name has a format vzdump-lxc-$ID-$Date-$Time.tar.zst.
    • The backup speed is quick. Using the "top" command it shows it is the command zstd running for the backup.
  • Restore Proxmox VM from backup – Here are the steps to recover your VM
  • VM ID:
    • One biggest problem is I cannot tell what the backup file is from the file name after I back up the files to another location. The backup file however contains VM ID on its filename. That is the only clue we can use to find out what the VM is on the original Proxmox.
    • The Backup Notes is useful actually. In the backup folders on Proxmox, it also create *.notes files if we create it on the GUI.
    • Maybe it's useful for me to create a text file along with the backup files to show what the files represents.
  • Question: why sometimes my backup files are not shown on GUI.
    Ans: the default backup storage is "local". We need to toggle that from the GUI. PS: the storage we changed cannot be memorized.

Am I compromised? If you need true remote access, set up a VPN that you connect to on your router.

Error 401: no ticket

Empty browser's cache. It works.

Check SMB Share availability before starting a VM

add a startup delay to your VMs and CTs if this is the only time you have this issue. Then set up a script in crontab to run @reboot that just waits x seconds, then remounts the share.
