[virt-tools-list] Best way to backup my VMs

[Bruno Lamps]

Hi,

Yesterday, I've run this command with cron, so I wasn't able to see if virsh
save worked OK. Now I tried it in the terminal and virsh save isn't working,
I think the problem happens before virsh restore. =D

I typed virsh save balance /backup/b.20110313, and the terminal is locked
for 20 minutes now, nothing happened. Where can I see some log of what is
happening? I've pasted here what I did today in terminal:




lamps at ubunteira:~$ virsh
Bem vindo ao virsh, terminal interativo de virtualização.

Digite:  "help" para ajuda com comandos
       "quit" para sair

virsh # list --all
 Id Nome                 Estado
----------------------------------
  - balance              desligado
  - bfw-t1               desligado
  - bunta11              desligado
  - firebunta-t3         desligado
  - zeus                 desligado

virsh # start balance
Domínio balance iniciado

virsh # list all
erro: dado "all" inesperado
virsh # list --all
 Id Nome                 Estado
----------------------------------
  1 balance              executando
  - bfw-t1               desligado
  - bunta11              desligado
  - firebunta-t3         desligado
  - zeus                 desligado

virsh # save balance /backup/b.20110413
