What's the recommended way to get the latest versions there? What exactly is your goal? If you just want some data snapshotted, I would think the safest way would be to put that data on a separate LVM partition on the host, passed in as a virtio device, and use LVM snapshots to back up the data. Be very careful with that. In theory it should work, but when you backup the snapshot, the load can bring down your server. Especially running virtual machines will suffer. That reminds me I still have to add this information to bug 712392 [1]... done.

run our business's mail server (W2003-DOMINO) as a KVM
Hi all, I posted a small question on #ubuntu-server: I noticed that ubuntu 10.04.2 LTS has quite old libvirt versions (libvir 0.7.5) which lacks many functions, like managedsave or snapshotting. What's the recommended way to get the latest versions there? jdepi ((ubuntu 10.10 has libir 0.8.3 which incorporates snapshotting etc)) nijaba jdepi: first look into backports to see if the version you want is there jdepi I'm a little concerned to run critical VMs on a non-LTS version... What is your opinion about this? nijaba jdepi: if it is not, then you have 3 choices: 1-upgrade to 10.10, 2-wait until next LTS(12.04), 3-Mess around with packages nijaba jdepi: I would have the same concerns as you jdepi thanks :-) but not very comforting nijaba jdepi: but only if I know I won't be upgrading that machine in the next 12month jdepi nijaba: i don't quite understand what you want to say? nijaba jdepi: non LTS versions are as stable as LTS ones, they just have a shorter life cycle jdepi aha jdepi ok, sorry, of course jdepi nijaba: it's 'just' a VM host, which will run our business's mail server (W2003-DOMINO) as a KVM nijaba jdepi: I see... try to discuss whith hallyn when he is around, as he has been doing most of the KVM/qemu maintenance since 10.04 jdepi nijaba: thanks, i'll try Presently, I will upgrade the VM host to 10.10, since a test machine has been doing it's hypervisor job for some weeks without a problem. I would be pleased to get some more remarks from people with more experience then mine :-). The network stack is running on a bridged bond to allow for virtio.
