[Xen-users] Running Redhat Advanced Server 2.1 on hvm

[Eric-Olivier Lamey <eolamey@xxxxxxxxx>]

  Hi,

  I was trying to have a working RHEL2.1 domU and found a mail sent  
on January 26th to xen-users by Nelson Chan. I am subscribed to the  
list but didn't have the original mail in my mailbox, so I'm sending  
this message with the same subject. Sorry if I screw up you mail  
reader's threading algorithm :)
  Anyway, after successfully installing a RHEL2.1 in hvm mode from  
our kickstart server, I tried two things:
  - running with non-hvm using the 2.4 xenU kernel provided by  
xensource. The system would boot although the console was stuck on  
the last init script launched. The init process would give weird  
messages (sorry, I didn't wrote them down) but the system could be  
reached by ssh. Some binaries (yum for example) would segfault. The  
upgrade to RHEL3's glibc worked, but I didn't want to go that way...
  - running with hvm and the default RHEL2.1 kernel. This didn't  
work and gave a kernel panic upon boot (I tried with -52 and the  
latest -71 release level from RH). I then took the vmlinuz and initrd  
files from the installation cd and used them. They are actually built  
from the same srpm and are found in the -BOOT package. I just had to  
tweak the initrd file so that it wouldn't launch the install after  
booting, but it worked.
  I'm using the system with this setup. As soon as I'll have time,  
I'll diff the kernel config files to try and locate the option(s)  
that make the regular kernel crash.
