My Windows machines fail to boot

[seyed]

Hey folks,
My Windows Virtual machines fail to boot; the time of failure appears to be random; but it is consistent across Windows distros (2019 - 10 - 2012). Currently I'm trying to troubleshoot a Windows server 2019 instance. The error that I'm encountering across the different distros is as follows:


‌Booting from DVD/CD.....
Boot failed: Could not read from CDROM (code 0003)
Booting from Hard disk.....
A disk read error occured....
Press Ctrl+ALt+Del to restart


At this point pressing Ctrl+Alt+Del is use less. Any help for debugging this issue is much appreciated. Also, I've tried all VIRTIO drivers; I initially spawned the VM with the

virtio-blk-pci

driver; I also changed the disk to

hdd

which did not solve the problem.

Hi,
please post the output of pveversion -v and qm config <ID> with the ID of an affected machine. When the failure happens, does it keep failing? Since when did you experience such failures approximately? It's a disk read error, did you already check the health of the underlying physical disks, e.g. smartctl -a /dev/XYZ? Anything in /var/log/syslog around the time the issue occurs?
