Hobbit on a virtual machine?
list Brian Thompson
Hi all, I was looking through the hobbit man-pages and I didn't see anything about running hobbit on a VM. We are currently doing this and we're having all kinds of issues with it. I don't know if it's an Ubuntu problem, a Hobbit problem, or a VMWare problem, but I thought I would check here first and see if anyone out there is running Hobbit on a VM, or even better, running it on Ubuntu on a VM and see if they've had any issues. Thanks, Brian Thompson

It shouldn't care what it's on, as long as it's got a network connection. There's nothing that low-level in hobbit to care what it's running on unless it's just a lack of system resources. What kind of problems are you having? Tod Hansmann Network Engineer

Henrik put together a VMWare appliance with Debian+Hobbit. It's in the Hobbitmon Files page on Sourceforge: http://sourceforge.net/project/showfiles.php?group_id=128058&package_id=200171 Roughly 250Mb... I've tried it, and it works just fine. Ralph Mitchell

The only problem we had with it was due to the time drifting... Because the VM does not run 100% of the time, the clock can fall behind. This was especially apparent on Fedora... See http://www.vmware.com/community/thread.jspa;jsessionid=2A2133B9464ADCBE6B6 C37F578A998E8?messageID=382726񝜆 -S

I remember reading about clock drift, but not how to fix it. That's useful, thanks... :) I didn't run it very long. I just wanted to see how well it worked, with view to setting up a "disaster recovery" image so that if our Hobbit server crashed and burned I'd be able to fire up a copy *really* quickly on any available hardware, such as my laptop. Given that the server is a single-733MHz-cpu DL380, I figured a VMWare instance on a 2GHz laptop ought to be able to keep up fairly well. :) Ralph Mitchell

Maybe you could sink to ntp from the vm, we do that for most of our vm's. Also I am running hobbit on feisty with out many issues.-Aaron> Date: Fri, 11 May 2007 11:53:07 -0500> From: user-00a5e44c48c0@xymon.invalid> To: user-ae9b8668bcde@xymon.invalid> Subject: Re: [hobbit] Hobbit on a virtual machine?> > On 5/11/07, user-7c93eddf04c3@xymon.invalid> <user-7c93eddf04c3@xymon.invalid> wrote:> > The only problem we had with it was due to the time drifting...

It seems to be unrelated to hobbit really, but I get odd crashes of the daemon, I had to run an fsck the other day after getting an image, and now that we had a VM server crash we can't restore ANY of our images of it, no matter what we do. I've personally restored some of the older images before and now none of them work. The other 50 or 60 VM's are all fine but this one just isn't having it. I just wanted to make sure there weren't any specific hobbit-related issues with running on a VM, so now I can probably dig into the next level or just move it off the VM entirely. Thanks for all the replies, Brian Thompson

It shouldn't care what it's on, as long as it's got a network
connection. There's nothing that low-level in hobbit to care what it's
running on unless it's just a lack of system resources.

While I haven't run that many VM's on a single server, I've had no issues with Hobbit running on them. My server is on a VM session and I have a range of clients also on VM sessions (Centos mostly but also Suse and W2K) Running latest hobbit. Regards Geoff
