Description James Hogarth 2017-11-22 10:33:24 UTC
Description of problem:
Trying to carry out a UEFI/Q35 based windows install results in a 100% CPU hang without the install actually starting. Tested but a win7 and win10 guest.

Version-Release number of selected component (if applicable):

How reproducible:
Every time with with default options, just changing block/net to virtio and cdrom to SATA and the boot to UEFI/Q35.

Additional info:

I did a scratch build of the current rawhide package:


This appeared to work fine on a Win7 install.

Can you please build this for F27 as a target? 

In addition please fix your %changelog as the versions don't align with the package version which made troubleshooting trickier than it should have been.

Comment 1 James Hogarth 2017-11-22 11:38:37 UTC
Hmm okay after testing windows installs ... on OVMF UEFI win7 reaches the point of "copying windows files" and then goes to a black screen with 100% usage (still better than 100% usage from the start and the installer never beginning) but it does install on win10... so the new build is still better than the current in F27.

So request still stands ... but for those testing look to win10 not win7 to test this.

Urgh scratch that ... a fresh build on that same UEFI firmware build hangs on start with 100% cpu still ...

No idea what's actually causing it.

If I get a diagnosis then I'll add detail.

I had a windows 10 (UEFI + Q35 too) working yesterday on Fedora 26 and after upgrade to fedora 27 failling to boot this morning.

I installed edk2.git-ovmf-x64-0-20171123.b3132.g646127c192.noarch and edited the VM to point to /usr/share/edk2.git/ovmf-x64/OVMF_CODE-pure-efi.fd.

My VM is now working again.
