I have a problem with fsfreeze that looks very similar to this, though I'm of course not 100% sure it's the same.
When I try to snapshot one server, fsfreeze-freeze hangs, and after having timeout'ed the qemu agent has crashed: # qm guest cmd 105 fsfreeze-status thawed # qm guest cmd 105 fsfreeze-freeze ^C << hangs, having to break out of the command # qm guest cmd 105 fsfreeze-status QEMU guest agent is not running # qm reset 105 --skiplock # qm guest cmd 105 fsfreeze-status thawed Host is Proxmox 5, VM is Centos 7 with Cpanel. This happens every time I try to snapshot the server. Other VM's on the host freeze fine without problem. I don't find anything interesting under /var/log. Please let me know if there is anything I can do to help debug this problem. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1807073 Title: qemu-guest-agent stop work when fsfreeze Status in QEMU: New Bug description: Create a live snapshot, we should first to fsfreeze the file system.
