[one-users] Interact with running VM

[Filippo Dalla Gassa]

Dear Tino,
thanks for your answer, but problems remain.

1) Network problem: I followed what 
"http://opennebula.org/documentation:rel2.0:cong" says.

   1. copied the vmcontext.sh file in the /etc/init.d directory of the
      disk used by the VM
   2. created the link to vmcontext.sh in /etc/rc2.d

However, when I start vm with opennebula, it seems opennebula assigned 
an IP from leases of the VN, but ping fails and if I enter the virtual 
machine via VI Client I see that the real assigned IP is totally different.

2) Snapshot problem: I made some tests and found this: if I try to make 
a snapshot directly with virsh snapshot-create it gives to me this error 
"Domain snapshot not found: Could not find snapshot with name 
'1294913536'" (I let him assign a name). The strange thing is that VI 
Client gives me no error message, like all goes well.  Moreover if I go 
into $ONE_LOCATION/var/<VMID>/images/disk.0/ directory I see two files, 
one-<VMID>-Snapshot1.vmem and one-<VMID>-Snapshot1.vmsn, and if try to 
revert to snapshot the VM through VI Client it detects correctly the 
snapshot.

Regards,

Filippo Dalla Gassa
