Description Tomasz Torcz 2008-07-29 05:48:21 EDT
Description of problem:
I have Fedora 9 x86_64 (on Opteron 150 CPU) in which I have installed VMware
Workstation 6.0.4. Inside VMWare I installed Fedora 9 i686, which I upgraded via
yum to rawhide.
Now, If I enable VMI support in VMWare Workstation (option called "Enabling
Paravirtual Kernel Support"), booting fedora fails at the beginning with:

initrd /initrd-2.6.27-0.183.rc0.git14.fc10.i686.img
   [Linux-initrd @ 0x1fad3000, 0x40c830 bytes]

Disabling VMI in VMWare workstation let Rawhide boot and function normally.
After googling I saw that similar problem was caused recently by missing "nopl"
opcode in some Cyrix CPUs. Is this a bug in fedora's VMI kernel implementation
or in VMWare Workstatio's emulation? 

How reproducible:

Steps to Reproduce:
1. Enable VMI in VMWare Workstation
2. Boot Fedora 2.6.27-rc0 kernel

Actual results:
Halt with above register dump.

Expected results:
Normal boot.

Fedora 10 with kernel 2.6.27-0.372.rc8.i686 boots on VMWare Workstation 6.5.0 build-118166 with VMI enabled.
