Univention Bugzilla – Bug 44083
Document QEMU suspend2disk / live-migration / running-snapshot issues
Last modified: 2017-06-22 16:57:12 CEST
+++ This bug was initially created as a clone of Bug #38877 +++ With QEMU-2.8 as used in UCS-4.2-0 the - suspend2disk (managedsave) state - live-migration from previous UCS releases to UCS-4.2 - restoration of snapshots of running VMs does not work reliably: Either the state is not restored completely and the guest-OS is stuck in some endless loop, or the guest OS crashes immediately and the VM is rebootet. For the UCS-4.2 release - an SDB article should be created to track the future progress and provide work-arounds - this should be mentioned in the release notes for UCS-4.2 - the update should be blocked if running or suspended VMs are detected - overwriteable by UCRV.

OK: preup script VM detection OK: UCRv update42/qemu Reopen: The SDB article explains the issues and mitigations quite well. I think it could be improved: * We can simply state that the VM host server may stay on UCS 4.1 until a fix is available * Improve the how-to style of the article, and not do into to much technical detail - although we have to state clearly what works and what does not work. I started an etherpad for my suggestions: https://etherpad-lite.knut.univention.de/etherpad/p/RXI96CtTAP
