Hi guys!


I would like to backup my DomUs via ftp. Unfortunately we don’t have LVM at this system. So I found this solution:


xm sysrq xenvm1 s

xm pause xenvm1

cp image /backup

xm unpause xenvm1


Ok tis works. But now I wanted to test this backup. I copied the cfg and changed the MAC adress.


I started the VM on the same Dom0 with xm create –c backup. The VM started correctly and changed the IP Settings. Now I got this error:  SysRq : HELP : loglevel(0-9) reBoot Crash terminate-all-tasks(E) ...


After a reboot the MySQL server is crashed.



So is this the right way? Or what is my mistake?
