Hi, the symptoms there sound rather different. The issue addressed by this patch was about a QEMU process getting completely stuck on I/O while the VM was live already. "completely" meant that e.g. connecting for the display also would fail and there would be messages like VM 182 qmp command failed - VM 182 qmp command 'query-proxmox-support' failed - unable to connect to VM 182 qmp socket - timeout after 31 retries in the syslog. The issue described in the forum thread reads like it happens only upon reboot from inside the guest and nobody mentioned messages like the above. > > If so, should this be investigated further or are there other issues? I have personally not had the issue mentioned in the forum, but quite a few people seem to be suffering from issues with Windows VMs, which is currently holding us back from upgrading from 6.x to 7.x on a whole bunch of customer clusters. I also haven't seen the issue myself yet and haven't heard from any colleagues either. Without a reproducer, it's very difficult to debug. > > Thanks, > > — > Mark Schouten, CTO > Tuxis B.V. > mark@tuxis.nl
