Hello...after we installed some kernel updates on our proxmox server we started getting following errors when we type qm list. we get this error for all qm commands. seems like there is an issue with the kvm on proxmox:

libqb: unix.c:79 [3] couldn't open file /dev/shm/: Is a directory (21)
libqb: unix.c:85 [3] couldn't open file /var/run/: Is a directory (21)

Is this a standard installation using our installation CD, or a custom install (do you run any other software on the host)?
 
here is the output:

yes we are still getting the error. we get the errors when we enter any qemu command. e.g qm list

I have no more ideas - Maybe you can do a fresh install on another node and test if you can reproduce the bug there?
 
problem was we had by mistake updated the group membership of root user. when i set the root user group to "root", all the qm commands started working. is the root user part of other groups. pls give us list of groups for root user.

Thanks,
