Re: [one-users] Running of VM ttylinux image
Hi, There was an issue [1] regarding this problem. It was fixed in the last maintenance release, so if you update to the last version the host will work properly.

Re: [one-users] Interact with running VM
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.

AFAIK, it ssh-launches, on the machine where the migration begins, a
command called migrate that (at least for KVM hypervisor) issues a
virsh migrate --live on the destination machine.
Only the devil knows why one of my machine can not be used as starting
point for a migration (and no, I was wrong in a previous post on this
list, I did not solve it :[ ).

Re: [one-users] live migration
Hi there,
since livemigrate functionality assumes shared FS, no transfer manager
call is performed by the OpenNebula core during livemigration.
Hope it helps,

I think this can help you [1]. To avoid your problem you can try to create the files /etc/qemu/krb5.tab and /etc/libvirt/krb5.tab In this way I solved the live migration problem. Have a good luck!

Hi, Yes, this could be possible.
