Question VMWARE Crashing Problem


I have a dell poweredge with a 60gb SCSI drive and 4gb of RAM running Red Hat AS 2.1 with VMWARE 4.0.2 and it sucks! I have two VM's they are both Red Hat AS 2.1 that are built to run Oracle Databases. My problem is that after a random amount of time usually less than 6 hours the vm's and the host lock up and become completely unresponsive and I have to hard reboot the box. Any assistance is greatly appriciated.

So just so I'm clear on this, you have a machine that boots up with Red Hat, and inside you run VMWARE with Red hat running inside a vmware virtual machine?

Yes I boot a Red Hat AS 2.1 Host and then from inside that host I run TWO Red Hat AS 2.1 Virtual Machines.

Wow, sorry for being obtuse, I just didn't think anyone would do that. (For curiosity, why do you? I'm fairly new to vmware myself so I wouldn't know the advantages of doing this).

As for the crashes, this may seem obvious and you may have done it already, but have your system logs shown you anything useful? or weird?

Do you have remote login capabilities on the host itself? Its something I've seen suggested here (which I've tried myself) is that sometimes when a machine is unresponsive, you can somehow still login remotely and check things....

It probably doesn't apply here but you never know...

The reason I am doing this is to be able to emulate both current copies of a production system for tools that I need to build and test ASAP and to be able to have a future version to test compatability issues and such. This really isn't my prefered method but I am tasked with making it work.

The only logs I have looked at are the vmware.log files and they are almost worthless. They seem to stop recording about ten minutes after the VM starts. Do you have any other suggested logs to look at. I am relatively new to Linux so any suggestions are appriciated.

And as far as logging in from a remote terminal...That is how I do most of my work on the box. But when it goes down I can't SSH, or even get a ping from it.

thanks for your help!

You're welcome, I just wish I could help more.

Ok. Now I understand what you're trying to do with those machines and I gotta say, that's a pretty neat idea You can test and trash the system, without trashing the system so to speak hehe.

Ok...your logs:

- most of your logs will be in /var/log.

- what I'd look at first is syslog, entries are dated and time-stamped so it SHOULD be easy to spot what was there right before the crash...you might see errors there which you can then google for (VERY effective when you see an error you don't understand) or post here if google doesn't help you.

- messages is also another file which might have something...

Anyway...its a good idea, as a newbie to poke around in that directory and look at the logs a bit...familiarize yourself. So if the two above don't do it (and I'm not 100% sure you'll find something) some clue might be in another log.

I didn't find anything usefull there. I think it is a application setting in VMWARE that is just causing it to lock up. I will keep looking...Thanks
