[Xen-users] DomU Lock on xm restore

[David Della Vecchia <ddv@xxxxxxxxxxxxxxxx>]

Here is my setup on this server:

Debian Wheezy (testing) with kernel 3.0.1 and xen 4.1.1 installed via apt-get 

DomU storage is lvm-based over iscsi

Everything else works fine as far as i can tell however when i do an xm save and then try to xm restore the domain does not come back fully, it gets added to the xm list but the cpu time used sits at 0.0 and when i console to it it does not respond to any keystrokes (except to escape out of the console)

I don't see any error messages in the /var/log/xend.log and xen-debug.log and i have logging turned way up. 

Here is the procedure i follow:

gibson:~# xm create zetas

Using config file "/etc/xen/zetas".

Started domain zetas (id=6)

gibson:~# xm list

Name                                        ID   Mem VCPUs      State   Time(s)

Domain-0                                     0  2048     4     r-----    932.5

zetas                                        6   512     4     -b----      2.1

gibson:~#

gibson:~# xm save zetas zetas.xmsave2

gibson:~# xm list

Name                                        ID   Mem VCPUs      State   Time(s)

Domain-0                                     0  2048     4     r-----    922.6

gibson:~# xm restore zetas.xmsave2 

gibson:~# xm list

Name                                        ID   Mem VCPUs      State   Time(s)

Domain-0                                     0  2048     4     r-----    929.3

zetas                                        7   512     4     -b----      0.0

gibson:~#

Here is the DomU config file as generated by xen-tools:
