Description of problem:
I want to install RHEL 4 on my Mac running OS-X 10.3 under Microsoft
Virtual PC 7. After mounting the CD image and turn on the virtual
machine, I get the linux loader prompt. I select 'linux text' and see
the kernel being loaded from the CD. After getting 'Ok, booting the
kernel.', Virtual PC stops the virtual machine with the error:
An unrecoverage processor error has been encountered.
This seems to be related to bug 136018. Seems like many virtual
machines don't like the 4G/4G kernel patch. If that is indeed the
case, I don't understand why it's the default.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Mount CD image
2. Start virtual machine
3. select any boot option
Actual Results: Virtual machine crashes
Expected Results: proceed with installation process
The 4G/4G kernel is not the default in RHEL4, so are you sure that is the problem?
No, not 100% sure. I know I can boot using disk1 of RHEL 3AS update 2. I haven't
tried any of the Fedora distributions, but the only problems I could find with
google related to Fedora Core & RHEL4 were somehow related to the bug I'm
I'd really like to get RHEL4 going with Virtual PC, I'm ready to try different
things but I just don't know where to start.
there's really not much we can work with here. The only thing I can suggest is
trying to disable various features (like execshield=0 etc)
I'll do more experimenting and try to bring more data. Is there a list
somewhere of the features that can be disabled on the loader command
line ? I tried execshield=0 but it didn't help.
actually, that should have been exec-shield=0
As virtualpc isn't something we list as a supported configuration, this isn't
going to get fixed anytime soon.
