FAQ

Stop all proxmox services

systemctl stop pve-cluster systemctl stop pvedaemon systemctl stop pveproxy systemctl stop pvestatd

 

switch to community repository

cat /etc/apt/sources.list.d/pve-enterprise.list 
#deb https://enterprise.proxmox.com/debian/pve buster pve-enterprise
echo "deb http://download.proxmox.com/debian/pve buster pve-no-subscription" > /etc/apt/sources.list.d/pve-no-subscription.list 
apt update

W: (pve-apt-hook) You are attempting to remove the meta-package 'proxmox-ve'!

cehck sources.list :)

 

 

unexpected property 'prune-backups' (500)

When for example Add: iSCSI Uncheck "Keep all backups" in "Backup retention"

 

 

Error: VM quit/powerdown failed - got timeout

qm stop VMID

if that complains about lock, remove the lock and try again

 

a used vhost backend has no free memory slots left

You have not turned on protection against thin pools running out of space.

serial console from command line

qm terminal <id}

enable serial console in guest

looks like this is not needed:

systemctl enable serial-getty@ttyS0.service

in /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="console=ttyS0 console=tty0"

ttyS0 is for qm terminal, tty0 is for the "console" buttion in UI

  1. debian based

update-grub

  1. redhat based

grub2-mkconfig --output=/boot/grub2/grub.cfg

 

add

serial0: socket

to /etc/pve/qemu-server/[vmid].conf and restart

 

agetty: /dev/ttyS0: not a device

systemctl status useless again, means the serial bit is missing from <vmid>.conf

TASK ERROR: command 'apt-get update' failed: exit code 100

subtle way of telling you to get subscription of at least change the sources list

Import vmdk to lvm

https://pve.proxmox.com/wiki/Qemu/KVM_Virtual_Machines#_importing_virtual_machines_and_disk_images

Can't apply changes to memory allocation

Maybe try enabling NUMA in CPU settings

 

 

Adding hardware shows orange

something is not supported (Options->Hotplug)

"Connection error 401: no ticket"

Login session expired?

can't lock file '/var/lock/qemu-server/lock-102.conf' - got timeout (500)

Maybe someone else has/had webui open

== TASK ERROR: Can't use string ("keep-all=0,keep-last=3") as a HASH ref while "strict refs" in use at /usr/share/perl5/PVE/VZDump.pm line 502. ==

Classic, means incorrect syntax in your /etc/pve/storage.cfg

 

The current guest configuration does not support taking new snapshots

You're using raw instead of qcow2. Convert: Hardware->Hard disk "Move Disk"

 

WARNING: Device /dev/dm-21 not initialized in udev database even after waiting 10000000 microseconds.

Until someone fixes it:

udevadm trigger

"connection error - server offline?"
