Hi All,
I tried to migrate VM's (--hvm as well as --paravirt) from one host to
another host with following settings
1. Both hosts are running same xVM (snv_79)
2. TCP port is open and ready to accept connection
bash-3.2# netstat -a | grep 8002
*.8002 *.* 0 0 49152 0 LISTEN
3. Both hosts are in same subnet
4. NFS shared storage.
Still I am getting errors. Please see /var/log/xen/xend.log output
a. For --paravirt and non-live

Are any additional settings required ?
I am able to migrate same domain on localhost.
Thanks,
