Can you please retry with current qemu.git master? I suspect that this is a duplicate of https://bugs.launchpad.net/qemu/+bug/1422307 and fixed in commit f0ab6f10 (a bug in the code handling VirtualBox's VDI image format).
In general, running VMs with image formats of other hypervisors is not recommended, both for reliability and performance reasons. You may want to consider using qcow2 or raw instead. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1428958 Title: random IO errors / data corruption in VMs (created and executed via virt-manager) Status in QEMU: New Bug description: I have recurring problems with VM installation and usage - data on VM disk gets corrupted at some point and it causes all sorts of problems - sometimes I cannot even install base system, other times some .so files are corrupt after isntallation, etc - totally random. I use virt-manager to create and run VMs. I have also tried creating VMs via virt-install, result is identical. If I use VirtualBox I have no such problems. My OS is Fedora 20 upgraded to 21, qemu and libvirt are installed from Fedora official repos.
