http://bugzilla.suse.com/show_bug.cgi?id=1057449 Bug ID: 1057449 Summary: [2.9.0] Qemu freezes when installing SLE15 Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: KVM Assignee: kvm-bugs@forge.provo.novell.com Reporter: riafarov@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- ## observation When trying to install SLES 15, qemu hangs and stops responding. No errors are in the logs. Appears only if perform installation with X11, in text mode issue doesn't replicate. Also, I cannot reproduce an issue with kvm disabled, but then it takes ages to complete installation. With older builds of SLE15 issue was there, but I could resolve it by restarting VM. With this build I can reproduce it in every run. ## steps to reproduce * Download iso using following link for x86-64: https://openqa.suse.de/tests/1149730/asset/iso/SLE-15-Leanos-DVD-x86_64-Buil... * Start installation with kvm enabled, e.g.: qemu-system-x86_64 -m 1024 -cpu qemu64 -enable-kvm -hda sle15_181.4.qcow2 \ -cdrom iso/SLE-15-Leanos-DVD-x86_64-Build181.4-Media1.iso * Click Next till Suggested partitioning page * Press expert partitioner button * Try to navigate in the tree on the left side of menu * Qemu freezes, process doesn't respond ## problem Qemu stops responding with SLE 15 iso and kvm enabled. I also was able to reproduce issue with different set of parameters like drive types, cpu, etc. -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.suse.com/show_bug.cgi?id=1057449 http://bugzilla.suse.com/show_bug.cgi?id=1057449#c1 --- Comment #1 from Rodion Iafarov --- Small update. Today I've tried upgrading using Virtualization Factory repo, still can reproduce it with qemu-2.10.0-399.7.x86_64. On other box I have it works fine with qemu-2.9.0-2.2.x86_64 -- You are receiving this mail because: You are on the CC list for the bug.

The most common case why VMs stop running is because you're running out of disk space on the host. If this only happens on that one particular machine, it's probably got to do something with that. -- You are receiving this mail because: You are on the CC list for the bug.

Can you reproduce this on one machine and give me access to it so I can take a look? -- You are receiving this mail because: You are on the CC list for the bug.

http://bugzilla.suse.com/show_bug.cgi?id=1057449 http://bugzilla.suse.com/show_bug.cgi?id=1057449#c4 --- Comment #4 from Rodion Iafarov --- Unfortunately it's my working laptop, so I can only easily provide VNC connection to running VM. I've checked disk space, there is plenty of it available. As I've mentioned above, it works if I select textmode installation of sle-15. Could you please suggest how to narrow down the issue, as I've tried adding verbose logging, but there are no errors in the logs.

So, could you please give a hint how to narrow down possible causes of the issue. I can easily reproduce it. Any ideas? -- You are receiving this mail because: You are on the CC list for the bug.

I can reproduce it and looks like freeze is caused by some kernel driver ( I get this lines using remote logging in installation )

This does seem to point to an issue which is already being addressed in boo#1057241. Marking as dup. *** This bug has been marked as a duplicate of bug 1057241 *** -- You are receiving this mail because: You are on the CC list for the bug.
