Where /lib/libvirt was moved from a btrfs fs (about 30GB free) Where /lib/libvirt was moved to a XFS fs did put a symblic link 'ln -s /myfs/libvirt /lib/libvirt' in place. Created a KVM - Win7 VM. During installation of the Win7 OS in the VM, very very heavy physical IO occured on the fs with btrfs. I couldn't manage to get the software installed in the running VM - had always funny errors (message: modified HW configuration. although nothing was modified). When the system/monitor was opened as well the kernel quited with Kernel Panic. The btrfs fs (/) was scrutinezed. Reproducible: Couldn't Reproduce Steps to Reproduce: I presume the fact that the checksums aren't equal for win7a.iso and win7b.iso is an indication for a severe IO issue. Actual Results: kernel panic and lost btfrs fs / Expected Results: would be nice having a vm with win7 operational Note: I do have two DVD devices connected: /dev/sr0 - USB /dev/sr1 - true SCSI the chechsums of the ISO Images copied from the same DVD via /dev/sr0 and via /dev/sr1 do never match (about 6 copy attempts from each). used commands: dd if=/dev/sr0 of=win7a.iso dd if=/dev/sr1 of=win7b.iso md5sum win7a.iso md5sum win7b.iso sha1sum win7a.iso sha1sum win7b.iso -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
