@Carl - the ddebs help if you need a crash report for example a program segfaulted. Then with the ddebs you can get more info of the symbols. But this BSOD crash is "inside" the guest, the ddebs on the Xen host would hot add additional information at the moment. @Carl - stick with .22 - the .23 in proposed is something completely different. I was also subscribing SMB as he might have a Xen environment ready to test things. @SMB - did you see any regression with the things you usually run? @SMB - it might need graphics reading "Windows, Live Boot, ..." so if you have console only guests could you try a graphical one? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752761 Title: Regression in vga handling ubuntu10.21 to ubuntu10.22 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1752761/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
RE: [Bug 1752761] Re: Regression in vga handling ubuntu10.21 to ubuntu10.22
Hi Christian, Thanks for your reply: Pt 2) LUBUNTU CD boot - not an option at this time - UAT / production Xen0 with other non Windows PV VMs running on them. Pt 1) Yes I can do some additional testing on a different R620 Xen0 / Xenial platform. Currently I can cause/remove the issue by just installing the 10.21 and 10.22 versions. This can be done live / without a reboot of the base Xen platform. From other testing I can tell you the recovery ISO CD is very slow to boot, but it did complete to initial screens previously (although I couldn't tell you exactly which of the newer versions of QEMU that was on). I can build an clean image from ISO fairly easily - do you have a preference for Windows 2008R8 vs Win7 Pro ? I believe it is the same issues, but most of my immediate issues are with Win Server VMs. I also have a Trusty system with the same issues - does that add anything if I can run tests on it? Finally (slightly dumb question) does the DBG version of the DEB (.DDEB) provide any additional information / crash reports - is that worth installing? Do you want me to work with .22 or the proposed .23? We can probably run development cuts from PPA, cut need a bit of risk control work at my end. @Marc - Does the BSOD screen shot / address / Windows MEM Dump file stuff give you anything?

This is the second qemu/xen bug for regressions in these security updates in one day - with none (=0) of them over the last two years - unlikely to be a coincidence. @Marc - I don't see an obvious change, but you have way more context on these changes since you have backported them. Do you have any info of a potential regression in them? Maybe the CVE-2018-5683 change? @Carl - your detailed steps are already great. Could you give it a try if the same applies to a unmodified (gplpv) and non-prepared/installed windows as well? Maybe by using an ISO of [1] in your already prepared setup - and if it fails as well sharing the commands you did for that as well? That would make it even better to reproduce. @Carl - we have another report on even Lubuntu iso's stalling. If you could (since all other parts of your setup are already ready) try the same with a boot from [2] - that is reported to hang with the new version.
