Thanks Daniel,
i did the next:
1- use dd command to get a copy from a vm:
dd if=00_16_3E_32_0F_0F of=copia-00_16_3E_32_0F_0F
2- then, ( probably big mistake :-( ) use virsh command:
virsh dumpxml 00_16_3E_32_0F_0F > ~/copia-vm.cfg
3- i modify the copia-vm.cfg and change the name field and remove the mac
address field, defined inside of the interface tag:
--------------------- virsh dumpxml output ---------------------
<domain type='xen' id='-1'>
<name>copia-00_16_3E_32_0F_0F</name>
<uuid>dd9fe09e1155f9223779b6c28bf43488</uuid>
<bootloader>/usr/bin/pygrub</bootloader>
<os>
<type>linux</type>
</os>
<memory>262144</memory>
<vcpu>1</vcpu>
<on_poweroff>destroy</on_poweroff>
<on_reboot>restart</on_reboot>
<on_crash>restart</on_crash>
<devices>
<interface type='bridge'>
<source bridge='xenbr0'/>
</interface>
<disk type='file' device='disk'>
<driver name='file'/>
<source file='/var/lib/xen/images/copia-00_16_3E_32_0F_0F'/> <target
dev='xvda'/>
</disk>
</devices>
</domain>
--------------------- virsh dumpxml output ---------------------
4- virsh define copia-00_16_3E_32_0F_0F, (am i (re-)define the domain
00_16_3E_32_0F_0F ???)
5- virsh start copia-00_16_3E_32_0F_0F (boot ok!, can get into the root
account, ping google.com, works! :-D)
6- but i don't need this domain anymore 'virsh undefine
copia-00_16_3E_32_0F_0F'
7- boot again the original vm:
[root@shutdown ~]# virsh start 00_16_3E_32_0F_0F
libvir: Xen Daemon error : GET operation failed:
error: failed to get domain '00_16_3E_32_0F_0F'
8- oops! :-(
9- i try to "recreate" the xml file,
a- [root@shutdown ~]# virsh dumpxml /var/lib/xen/images/00_16_3E_32_0F_0F
> original-vm.cfg
libvir: Xen Daemon error : GET operation failed:
error: failed to get domain '/var/lib/xen/images/00_16_3E_32_0F_0F'
b- [root@shutdown ~]# virsh dumpxml 00_16_3E_32_0F_0F > original-vm.cfg
libvir: Xen Daemon error : GET operation failed:
error: failed to get domain '00_16_3E_32_0F_0F'
is possible bring to alive the domain 00_16_3E_32_0F_0F?
thanks!
