[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] I have killed hypervisor. wow
Greetingsall my pv domains have failed today after reboot (hvm domains are ok). I found out that virtual block devices just stopped mounting to guests. Then I tried to destroy failed domains and got a lot of messages to dmesg like: blk_tap: Bad number of segments in request (179) #snip 1511 messages blk_tap: unknown operation [152] #snip 1526 messagesThen dom0 froze dead producing the above output only. After the reboot everything was the same except dom0 kept produce same output for a couple of minutes, and domU finally was destroyed. after 'xm create -c ubuntu810' (domain falls into initramfs shell) hypervisor dmesg shows: blktap: ring-ref 2047, event-channel 4, protocol 1 (x86_64-abi) tap_frontend_changed: backend/tap/1/51712: prepare for reconnect blktap: ring-ref 8, event-channel 9, protocol 1 (x86_64-abi) guest dmesg: 0.403082] device-mapper: uevent: version 1.0.3[ 0.403297] device-mapper: ioctl: 4.14.0-ioctl (2008-04-23) initialised: dm-devel@xxxxxxxxxx [ 0.535802] xvda: #it's not mistake. dmesg just ends output. I destroyed domain again and everything repeats.I think this is caused by 8.10 kernel, which has updated to 2.6.27.7.14 or 16 recently. But I have no idea why this keeps crashing the system. Any ideas? domU config: kernel = "/usr/lib/xen/boot/pv-grub-x86_64.gz" extra = "(hd0,0)/grub/menu.lst" memory = 2048 vcpus = 2 name = "postgres1" uuid = "5bb1d470-ae11-389f-b49a-49ff2a84a9f3" vif = [ 'mac=00:16:3e:36:7f:a9, bridge=eth0' ] disk = [ 'tap:aio:/var/lib/xen/images/postgres1.img,xvda,w' ] p.s. please, tell me, if I should provide more information p.p.s. thanks to Mikhail Kozyrev for spelling _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
