Hi,
I'm triyng to build/install Kemari on CentOS 5.3 x86_64. I have followed
instruction found here http://www.osrg.net/kemari/usage.html
I have successfully build and installed Xen and Kernel. Now I'm trying
migration of HVM guest running CentOS 5.3 i386.
Inside the guest OS I've compiled and installed PV drivers from Kemari
source tree. So far so good.
Usual Xen live-migration is working properly too. But when I try to use
Kemari migration I receive following error:
[root@kemari02 python]# xm migrate test2 kemari01 -k
Error: /usr/lib64/xen/bin/xc_kemari_save 5 4 0 0 4 failed
Usage: xm migrate <Domain> <Host>
And here is what I see in the log:

So what can be done to make it working? Is it better to use
Kemari/kernel from Mercurial repository at xenbits?
And in general what is current Kemari project status?
Thanks,
Eugene
