FAQ

Proxmox API call failed: Couldn't authenticate user: zabbix@pve

Funky characters in password string?



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

 

 

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

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"
