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?

 

Best regards,

 

Stefan
