Paul Durrant writes (RE: [qemu-upstream-unstable bisection] complete test-amd64-i386-freebsd10-i386): I thought this was fixed. I posted the fix over a week ago and it's applied: Looking at the most recent tests it appears that there is a combination of heisenbugs: Many recent flights (eg 35087) have: test-amd64-i386-pair 17 guest-migrate/src_host/dst_host fail pass in 34247 And 34247 has other problems with migration. Looking at 35087/test-amd64-i386-pair/17.ts-guest-migrate.log I see: Parsing config from saved xc: progress: Reloading memory pages: 7168/1310725% xc: progress: Reloading memory pages: 13312/131072 10% xc: progress: Reloading memory pages: 20480/131072 15% xc: progress: Reloading memory pages: 26624/131072 20% xc: progress: Reloading memory pages: 32768/131072 25% 2015-02-23 09:37:11 Z command timed out [400]: timeout 430 ssh -o StrictHostKeyChecking=no -o BatchMode=yes -o ConnectTimeout=100 -o ServerAliveInterval=100 -o PasswordAuthentication=no -o ChallengeResponseAuthentication=no -o UserKnownHostsFile=tmp/t.known_hosts_35087.test-amd64-i386-pair root@10.80.249.149 xl migrate debian.guest.osstest itch-mite status (timed out) at Osstest/TestSupport.pm line 397. The same in 34696. It may be that this will eventually pass. It would be nice to know why this sometimes fails! Ian. ___ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

If it is not soon, I would prefer to revert the patch for now to unbreak tests. I'll hopefully have something in the next day or so. I'm working on the stubdom problem at the moment.

This prevents the guest from mapping these pages (they are in a well known location) and attempting to attack QEMU by synthesizing its own request structures. Hence, this patch modifies configure to detect whether the API is available, and adds the necessary code to use the API if it is. upstream-commit-id: 3996e85c1822e05c50250f8d2d1e57b6bea1229d Signed-off-by: Paul Durrant paul.durr...@citrix.com Signed-off-by: Stefano Stabellini stefano.stabell...@eu.citrix.com Acked-by: Stefano Stabellini stefano.stabell...@eu.citrix.com For bisection revision-tuple graph see: http://www.chiark.greenend.org.uk/~xensrcts/results/bisect.qemu- upstream-unstable.test-amd64-i386-freebsd10-i386.guest-localmigrate.html Revision IDs in each graph node refer, respectively, to the Trees above.
