Ubuntu 12.04 as VM Host?

Postby smccloud » Mon Mar 11, 2013 5:50 am

In the past I have tried to run KVM on my Ubuntu 12.04 HDA so I can run a single VM under it. However it didn't work so well as "/etc/networks" got overwritten. Is this still the case or am I able to setup my Ubuntu HDA install as a KVM host now?

Not sure anything has changed. Have you tried Proxmox? It works well for me. My HDA is a VM :)

Problem with Proxmox is that install drivers for Windows is rather hard. And I need one machine setup running Server 2003R2+ for WSUS.

Ah. Have you tried the latest version? It was just updated recently.

Thats what I just downloaded. Installing now. Still uses the same version of the KVM drivers though. Someday soon I need to build a "new" home server with a faster processor than the little AMD Turion II Neo in my HP MicroServer (and use the MicroServer as my router). Probably a low end Core i3 w/ virtualization support.

Yea, I am running Proxmox on an AMD 8-core with 16GB RAM. My HDA is virtualized now :)

I'd be happy if I got another Core i5 3570k (quad core) and 16GB of RAM for my virtualization server. Same basic setup as I have in my desktop and it would fly for Amahi & PIAF.

My HDA is up and running. Had one glitch where it couldn't reach the network though. Not sure what caused that. I do know, I cannot use a VIRTIO disk as the HDD on my Windows Server 2003 R2 machine, cannot get it to boot once I install the VIRTIO drivers :(

I tend to stay away from the VIRTIO disk type. I use mostly IDE and SATA for mine. I also have my virtual HDA linked to use 2 physical drives for Greyhole. Works well.

I can switch between F14 and Ubuntu HDAs. I shut down one and bring up the other. Run Greyhole to catch up on the file changes. I have most of my shares virtual, so file copies live on the physical drives but the links are on the virtual drive if that makes sense.

A lot of my setup is based on the Virtualization topic area where sgtfoo helped explain it.

I had to drop Proxmox. I was getting write speeds of around 1MBps no matter what disk type I used. Now that its a physical box again, my write speeds are much improved.
