Description Louis van Dyk 2016-08-02 13:06:06 UTC
Description of problem:
On Fedora 23 and now also on Fedora 24 x86_64, my Windows 10 Guest (also 64 bit) will work for a randon time, and then the GUI will freeze.  I am able to ping the Guest, and map drives to it and read and write files.  However, the GUI is completely locked up and never recovers.  I have thought it is more likely to happen when the browser is open (Edge, and also occasionally with IE), but I cannot be certain of that.

Version-Release number of selected component (if applicable):
Please note that it did this on Fedora 23 as well ...

My GUEST was originally set up as a Windows 8.1 device, and was upgraded to Windows 10.  I have not changed any VM settings.

I have installed all Guest Drivers from virtio-win-0.1.118.iso

The RPMs installed on the host are:

How reproducible:
It is random.

Steps to Reproduce:

Actual results:
The GUI freezes.  I can map drives and access the file system via the network.  I usually have to issue the "virsh destroy" command, and restart.

Expected results:
The GUI should never freeze.

Hi Louis, sorry this didn't receive an earlier response. Are you still seeing this with latest packages?

Comment 2 Cameron Harr 2017-03-20 20:45:39 UTC
We have seen similar issues with multiple Windows2008 VMs since some time last year. Host is running RHEL 6.7-6.8. Freezes may be hours to weeks apart. A network load seems to be a catalyst, but that's circumstantial. 

When freezes happen, there are no errors in /var/log/messages or the VM log in /var/libvirt/qemu/. Dmesg does show a number of audit messages followed by interfaces being disabled and then placed back into forwarding mode:

type=1305 audit(1489574942.319:479997): audit_pid=36710 old=0 auid=0 ses=69210 res=1

While the VM is frozen, I can get some ARP communication from it, but nothing else. From the host, I can ping other hosts on the same subnet, so my hypothesis is the virtual interfaces on the VM have gone out to lunch.

Comment 3 Cole Robinson 2017-03-20 20:51:25 UTC
Cameron, RHEL6 host virt is drastically different than a Fedora virt host at this point, so it's more appropriate to file a bug like that against RHEL, there's a good chance they are not the same issue

Comment 4 Cameron Harr 2017-03-20 21:02:56 UTC
My apologies, you are right. I was looking at so many issues I didn't realize this one was Fedora-based.

Comment 5 Louis van Dyk 2017-05-11 10:15:44 UTC
Hi Cole

Somehow I missed the needinfo.  No, I haven't noticed this in so long I'd actually forgotten about it.  Thanks for all your tireless efforts!
