qemu discuss - Apr 2009 - qemu 0.10.2 and Solaris snv111 64 Bit /"unexpected erratum #100"

Hi

I''ve installed Solaris snv111 in a QEMU virtual machine using qemu 
0.10.2 with kqemu 1.4 enabled. The installation worked without problems 
but after rebooting from the virtual disk Solaris panics:

qemu usage:

 /opt/qemu_0.10.x/bin/qemu-system-x86_64 -net user -net nic -usb 
-usbdevice tablet -L /usr/local/share/qemu_0.9.x -boot c -m 1024 -net 
nic,model=rtl8139 -net nic -net nic -redir tcp:1136::22 -name 
''Solaris/Nevada_(ssh_port:_1136)'' -hda
/data/qemu/harddisk/nevada.hdd
-serial stdio

kqemu 1.4 was enabled for  User Mode

Console output:

Solaris 10 snv111 runs fine in the QEMU 0.10.2 emulating a 32 Bit CPU.


My Environment:

Hardware: Thinkpad T61p

Host OS: OpenSolaris 06/2009 (SunOS t61p 5.11 snv_111 i86pc i386 i86pc)

QEMU 0.10.2 (sources from qemu.org compiled in OpenSolaris) with kqemu 
1.4 enabled for User Mode


This message is only for information because there''s a bug for this
error

http://bugs.opensolaris.org/view_bug.do;jsessionid=5f53a0a674f29fffffffff17caa8b9711de8?bug_id=6692125

where it states:

"As a first step, tweaks will be made to the trap code to not always 
panic on erratum 100 condition to determine if the workaround can be used in
processors that are not supposed to have the erratum. If so, we will 
have useful data to give to AMD. I''ve previously tried to gather this 
info with a one-off debug solaris build but was unsuccessful because the 
problem could not be reproduced."

Bernd
