Description Martin Krizek 2012-04-05 12:23:29 UTC
Description of problem:
Using qxl in virt-manager, the mouse cursor is not displayed in KDE in Fedora 17 Beta RC3. However, once one logs out of the KDE session, the cursor appears and is visible from that point also after logging into the KDE session again.

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

How reproducible:

Steps to Reproduce:
1. Choose qxl in virt-manager
2. Boot and log into KDE
Actual results:
The mouse cursor is not visible

Expected results:
The mouse cursor is visible

Comment 1 Martin Krizek 2012-04-05 12:24:53 UTC
Proposing as F17 Beta blocker, since it makes KDE desktop unusable.

Comment 2 Jaroslav Reznik 2012-04-05 14:40:04 UTC
I can't reproduce it as my virt-manager does not want to grab mouse - any hint here?

Comment 3 Adam Williamson 2012-04-05 15:08:04 UTC
I can't reproduce with qxl/spice, works fine.

reproduced with qxl/vnc, which is never a default config.

> reproduced with qxl/vnc, which is never a default config.

We can't assume that in general - since qxl provides basic VGA capabilities when used without SPICE, it is perfectly reasonable to use QXL + VNC. So while virt-manager doesn't do this by default, it is acceptable for apps to enable QXL by default.

Changing to QEMU on basis of Cole's URL

Comment 9 Adam Williamson 2012-04-06 04:10:13 UTC
dberrange: as far as blocker status goes, we mostly consider fedora's 'supported vm stack', which is taken to be virt-manager / libvirt / qemu / kvm.

Discussed at 2012-04-05 go/no-go meeting - http://meetbot.fedoraproject.org/fedora-meeting-1/2012-04-05/gono-go_continuation_f17_beta_rc3_part_two_or_three.2012-04-05-15.00.html . We agreed that as the qxl/vnc combination has never been default in the supported stack (see above), it's easy to 'work around' this bug by switching to cirrus/vnc or qxl/spice, and the bug is not in the guest but the host (and so we don't gain much by fixing it in the release images) this bug is rejected as a blocker. It is not accepted as NTH, for the reason that fixing it in the images doesn't actually change much. Anyone running a host can be expected to have the latest updates on the host.
