Based on this message, it is qemu that is refusing to do the pivot, but I don't know if that is because of permissions on the destination file, or something else (that is, it may still be a libvirt bug for not putting things in the right state for the qemu command to have a chance of succeeding). What distro are you using? Is AppArmor or SELinux at play, where temporarily getting that out of the way might change things?
I'm using Gentoo. There is no selinux or apparmor enabled on this machine. Should i file a bug report?
A colleague of mine pointed me in the right direction. There was a cdrom defined in the virtual machine. After removing it the process runs as expected:
+ virsh blockcommit kaltura vda --active --verbose --pivot Block Commit: [100 %] Successfully pivoted
It seems the real cause is qemu 2.2.0. The error reaccurred the other day even with only one disk configured. After downgrading to qemu-2.1.2 no problems so far. cheers t.
