Red Hat Bugzilla – Bug 217635
VTI domain sometimes fails to display SDL graphics window
Last modified: 2018-10-19 15:09:56 EDT
Description of problem:
When I test keeping create/destroy in VTI domain graphical mode
(specyfing sdl=1, nographic=0),
Sometimes qemu-window creation failed at creating VTI domain.
I try to create VTI domain 618 times and 42 times are failed to create
Such a failed domain has no status and the cpu time isn't gained as below.
#xm list vm1
Name ID Mem(MiB) VCPUs State Time(s)
vm1 10 512 1 ------ 0.0
Version-Release number of selected component (if applicable):
RHEL5 Beta2 Milestone 8
42times in 618times of creating.
Steps to Reproduce:
1.xm create <config>
2.xm shutdown <domain>
Occasionally qemu-window was not started.
VTI domain is always created normally with qemu-window.
Applied aron's patch and selinux-policy-2.4.2-9.
But the same issue occured.
Created attachment 142353 [details]
log files related with xen
Created attachment 142354 [details]
the sysreport when the issue occured
I tested this with the following script:
while : ; do
xm create rhel5_x86_64;
xm destroy $x;
The read was to let me make sure the window was created before destroying the
domain. I ran it 700 times, and the window was created each time.
Also note that the title of this BZ is misleading. The bug is not with the
status not appearing, but the bug is that the qemu-window was not created.
It looks like this one is actually fixed, and the IT was closed long ago. I
think it just wasn't in the system to go ON_QA -> CLOSED. I'll just close it as
CURRENTRELEASE for now.
