Hello,
I've a got a Linux VM running as follows:
Boot disk is ide1, whereas scsi0 is used for storage, on my LVM "images". I now want to move the qcow to my images LVM storage as well. It seems I screwed things up somehow. I wanted to create specifically a 256M boot disk and I could not do that for LVM storage from within the GUI; it needed to specify 1G at least.
So I tried creating a lv images:vm-106-disk-2 by hand (ie, without using pvesm, which I found later on, but rather directly lvcreate) and then edited the vm conf file to insert a line as follows:
The problem is the the system would not start, throwing the following error:
I removed the line scsi1 from configuration and removed the lv as well. The system booted up fine. Then I found out the pvesm command. While the VM was stopped, I used the following:
At this point, I expected that the vm configuration would be updated to reflect this change, but nothing happened. I had to manually edit the .conf, by adding the following:
Trying to start the VM throwed the following:
Any idea what might be wrong here?
