virtio-blk XFS corruption

2010-09-25 Thread Peter Lieven
Hi all, we experience filesystem corruption using virtio-blk on some guest systems togehter with XFS. We still use qemu-kvm 0.12.4. Does someone remember if there has been a fix submitted meanwhile? It seems that 64-bit Ubuntu LTS 10.04.1 is affected as well as an older openSuse 11.1 system wit
