Hello list, I've got strange phenomenons with migrations. I think it's a bug, but am not sure, so i am asking for your help to find this ou, please ;) First the construct: Two HP DL180G5(xen0,xen1) with dual-quadcore each, 8G RAM. On each a dom0 with selfcompiled(because of network drivers) gentoo-sources-xen-2.6.27_amd64 and Xen 3.3.0. The installation is completely the same (rsynct), only different in ip and hostname. Both share a drbd0(v8.3.0) device. On it an lvm with one lv per vm. Now what's the problem: If i migrate a running vm(mx1-smartnet-de) from xen0 to xen1, it seems to work. I could do a "xm migrate mx1-smartnet-de xen1" without any interuption while having a ssh-connection to the vm and downloading a kernel-source in it. Then i did a "xm migrate mx1-smartnet-de xen0" on xen1 to move it back again. After that, the vm freezes at 100%CPU and that's it! Can't connect to it any more, whether via ssh nor via vnc/fb or console. Only "xm destroy" could help, "xm shutdown" has no impact. For debugging, i added the concerning parts of the xend.log from each and the kernel-configs, so that you could try to help me find the prob perhaps in the logs? Just after having started the vm: xen0_after_start_of_vm.log Then after the first migration: xen0_after_migrate_to_xen1_of_vm.log xen1_after_migrate_to_xen1_of_vm.log And last, after the reverse: xen0_after_migrate_back_from_xen1_of_vm.log xen1_after_migrate_back_from_xen1_of_vm.log I don't believe it is a drbd/lvm problem, because drbd keeps in "0: cs:Connected ro:Primary/Primary ds:UpToDate/UpToDate C r---" and there are no lv-concerning log-entries in syslog. There are of course errors concerning "retry suspend domain failed", but there's no hint, WHY this has got failed?
