Hi,
I have been using Ubuntu for a long time but haven't used it as a serious virtualization host until now. I switched my main desktop away from Windows and am trying to get some kind of reliable VM management set up. Been running into a lot of problems though. I'm not entirely sure which direction to go, so I apologize that this question isn't going to be terribly pointed. Still, I will be as specific as I can.
Problems I'm having with virt-manager are primarily that I can't get it working at all. I try to create a VM, import or create storage, and start it, but I receive various errors depending on what I've tried to get it running. I have verified that my CPU (Opteron 1385) supports SVM and that the feature is enabled in firmware. Somewhere along the way, GRUB added an option (as default) for "Ubuntu with Xen Hypervisor" and checking ps in a terminal shows that xend is indeed running. However, when I try to setup a VM in virt-manager, I run into two errors. One states "Unable to complete install: 'Cannot recv data: Connection reset by peer'" and the other states "Error polling connection 'xen:///': internal error: received hangup / error event on socket". I'm assuming I need to better understand some client-server paradigm Xen uses but I'm not there yet and any help in just getting to the point where I can reliably create and run VMs would be a huge help to me. It's difficult to learn past frustration and I'm hoping others here understand the feeling of just wanting the thing to work for now so you can sort out details later.
VirtualBox will run VMs but I encounter a problem where the entire host system will lock up. I can't seem to restart lightdm and the only way to reliably get a functional system back is with a hard reset via the front panel button on the tower. Also, VirtualBox will not start guests at all if I'm booted to the "Ubuntu with Xen Hypervisor" option in GRUB. I suspect this is because when I do this, the entire OS environment is running as a Xen VM and so VirtualBox would be running nested, but I don't know that for a fact.
Ideally I would like to correct all of these problems so I can use any hypervisor I want, but I'd be happy with one or the other as long as I understand exactly how to run it without show-stopping problems. Please let me know if you need me to provide screenshots, error text, logs, command output or anything else.
Thank you.
