Chris,

Thanks for getting back to me! I can't believe I didn't think about that..

With the release of Xen 5 from Citrix (for free!), I changed my direction for this customer.

Funny, though. Your article made me get totally immersed in the drbd stuff. I had always wanted to get more into the cluster stuff, but just never jumped in and started reading. Now, the drbd stuff (with Heartbeat) just looks like it could do SO much.

Again, thanks for your post!

..and if you haven't seen the new free stuff from Xen, you should check it out. It does the VMotion stuff.. (which is what I was really interested in for this customer).

Thanks all,
ipguruu99

Yes, Xen is quite nice... unfortunately a lot of my hardware doesn't play too well with it (no VT bit). So I use it when I can.

Also an FYI for those playing with VMWare Server 2.0 and all this HA/DRDB stuff. The workaround for moving the VM between machines is a little different. You're no longer prompted in the GUI for the 'always keep' or 'always create' options. So moving the VM between them can be a problem.

The fix is to add the following line to the .vmx file for each of your virtual machines. It will keep the UUID (mac address ,etc) the same as you shutdown/suspend and move between hardware.

uuid.action = "keep"


I'm still working on some details for doing all this automagically on vmware 2.0. Will post when done. Right now my play environment is a pair of Dell 2850's using the Proxmox bare metal install. Then I installed VMware Server on top of it. So I can use OpenVZ/PVE and VMWare at the same time on the same host. Pretty spiffy.

--Chris
