Re: [Qemu-discuss] problem with virtio disk driver
Thinking it might be because I had an old version of qemu I upgraded qemu to v 2.6.0. And got the same behavior. libvirt 1.2.20 is also pretty old, current one is 2.3.0, maybe you can try that.

Re: [Qemu-discuss] problem with virtio disk driver
I'll try to update libvirt, but I am not sure that would make any difference; the problem seems to be related to the virtio disk dirvers which are provided by qemu. I even tried taking libvirt out of the picture and creating the VM using qemu cmdline...same problem Anyway, about the Embedded Linux Host - it is compiled for x86 architecture and currently is running kernel 4.7.8 (previously 3.18) Hope this helps, Andrei On Fri, Oct 21, 2016 at 2:59 PM, Aleksei wrote: > > Thinking it might be because I had an old version of qemu I upgraded > qemu to v 2.6.0.

Just in case this sparks anyone's interest, the problem is still not solved, not even upgrading the host's kernel form 3.18 to 4.7.8 There is something I'm missing here..

[Qemu-discuss] problem with virtio disk driver
I just ran into a problem I can't make heads or tails of, so I'm hoping to get some help here. I have a custom built Embedded Linux as host, running qemu-kvm 1.1.2 and libvirt 1.2.20 I'm creating a domain with the following config: myVM 2097152 2 hvm destroy restart restart Granted the guest OS I'm installing is again a custom Linux with some software running on top ..so It's not a well known OS...but I'm hoping that does not matter much.
