The issues we had were do to a disk failure , and a new sysadmin changing out the wrong disk slot.


Hello
I've 3 windows KVM that are not working. in console that are stuck at:
"Booting from Hard Disk..."

there a /etc/pve/qemu-server/ config file :

This issue still occurs.

We've a win7 kvm that runs fine on a different pve host.

I tried to backup that kvm and restore to the host having issues, and the same problem occurs stuck at : "Booting from Hard Disk..."

Then I tried converting the disk to qcow2 , backup and restore and still won't boot.

Is anyone else having this issue?

This is strange, maybe can you try with disk option = "cache=writethrough", or "cache=directsync".

I have seen this behaviour a long time ago with some 4K disk drives. (what is your physical disk models ?)
 
Re: Windows 7 KVM's not starting.

Hi Sprit.

I tried the 2 disk settings and those did not solve.

The disks are on a 3ware raid 10 array.
they are WD RE4 1TB

Note we've been using those for a long time.

And the win7 kvm was running on main cluster using those for months with out an issue.

the images are stored on nfs . I do not see a /dev file that gets used .

is there a dev file somewhere or should i run qemu-img check on the image file at nfs storage?

qemu-img check reports no errors....
Code: 
qemu-img check vm-505-disk-1.qcow2
No errors were found on the image.

If you've more suggestions let me know. Later I'll try some other random things and do more searches.....

i'm so sorry, can you please give me more details about this issue, because i had same problem in win7 kvm, stuck at Booting from hard disk....

i use only one harddisk, 1TB, SATA at SATA 0 port.
 
Re: Windows 7 KVM's not starting.

we have raid 10, and one disk was failing. the wrong disk was attempted to be replaced.. I thought that was the cause of the issue. it may not have been the reason for the kvm not starting.

months after that we found the windows disk was 100% full. it would start on the existing system, but not when the system was backed up and restored.

we re installed the one program we had running on that kvm to a new kvm.
