virtual server on my rhel 5 not starting
Sometime ago installed my RedHat 5 with xen. Then I needed to create a virtual server running RedHat 4 in it, all needed to be 64 bit because Opsware required 64 bit RHEL AS4, so had to come up with an inexpensive solution. Got Intel Quad from Dell for $400 with 8gb ram, inexpensive desktop, installed RedHat 5 on it, then created xen virtual server in it running RedHat AS 4 for Opsware, of course opsware is not supported under XEN as a virtual server and it would not run under RedHat 5, so I had to hack it a bit to get it working, actually to get it installed is quite simple. Anyway so I had my RedHat AS4 vm running then I did notice that my desktop running all of that rebooted the other day, but my opsware virtual server did not start. With XEN I am not that familiar so I had issues starting it with command line, so I was ending up bringing xdisplay back to my pc remotely just to start it up. Well what it turned out that I don’t have to do this anymore. I was playing around with starting it up and why, I can do it automatically.
Anyway solution to start it up was very simple, on my RedHat 5 hyperviser I had to go to /etc/xen directory, there is directory called auto, and there is a config file for my virtual server called opsware (name of that virtual server) so to get it automatically started I needed to create a symbolic link inside that auto directory that pointed to that opsware config file.
Simple and easy, not when my desktop reboots my xen vm starts automatically.
