I rebooted the server, and the error changed to :

Error: (14, 'Bad address')

Same thing happens when I want to start another DomU which I had created using the virt-manager DomU creation interface. It had worked perfectly before..

Searching such an error in the mail archive didn't yield many results.. I suppose this is not a common problem. Can anyone shed a light to it maybe?

BTW: cpu arch is x86_64

new xend output:

Hi everyone,

I generated my own DomU guest using opensuse's yast dirinstall and stored it on a seperate iscsi target. I created it as a DomU on my Domain0 (2.6.25.16-0.1-xen kernel) successfully, using the following configuration:

name = "vm01-opensuse11-base-LAMP"
memory = 256
kernel = "/boot/vmlinuz-xen"
ramdisk = "/boot/initrd-xen"
root = "/dev/xvda1"
# iscsi disk: lun 0 is root partition with ext3fs, lun 1 is swap
disk = [
'phy:/dev/disk/by-path/ip-<ip-number-omitted>:3260-iscsi-iqn.2009-01.<qualifier-omitted>:vm01-opensuse10.3-lun-0,xvda1,w',
'phy:/dev/disk/by-path/ip-<ip-number-omitted>:3260-iscsi-iqn.2009-01.<qualifier-omitted>:vm01-opensuse10.3-lun-1,xvda2,w'
]
extra = "console=xvc0"

No problem so far. Then I migrated this DomU to my other Dom0, say host B, which has exactly the same xen kernel version. The guest images are available from this one too, following the same /dev path, and the same guest configuration file is copied to the same xen path (/etc/xen/vm). Both machines have identical xend-config.sxp and they have the same xen version, which is 3.2.0.

When I issue "xm migrate --live <id>" on host A, the DomU seems to be properly migrated. However, when the migration completes (when the DomU disappears on host A), the DomU goes into the paused state, which is not an expected behaviour. When I manually unpause it, although xm list says it's in blocked state, it hangs. I cannot get response from "xm console <id>". It cannot be shut down either, so I have to use xm destroy.

So for troubleshooting purposes, I tried to create the DomU directly on host B first, disregarding the migration part. I issued the "xm create vm01", just like I did on host A. Host B gave the following error:

"Error: (38, 'Function not implemented')"

I append the xend.log below, which didn't really tell me any clue.

Has anybody encountered such an error before? Any help is appreciated!

Cheers,
Ercan
