xen discuss - Dec 2007 - Failed boot of xVM on an AMD Turion 64 X2 TL-52 based laptop (with 4GB RAM) ...

Hello:

I successfully installed Solaris10 nv77 x86 on my Compaq NX6325 laptop
with the following specs:

- Mobile AMD Turion 64 X2 TL-52 (dual core 64bit).
- 4GB RAM.

The installation destination was an external 120GB USB 2.0 drive.

I was able to successfully boot into regular Solaris, but not into xVM
Solaris. Meaning, after highlighting the xVM menu item and pressing enter,
the screen turns black, as if about to book, then a quick burst of text
pops up and disappears (so fast that you cannot see it), and then the
screen goes blank again. And thats the end - I have to power cycle.

Is there any way to debug this? Should nv77 work on this model
(or later versions)? Is there a hardware compat list?

I''m looking for an environment to practice on. Any relatively
inexpensive
platform suggestions welcome too, (even from Sun''s site) if you know it
to work with Solaris Xen in it current state.

Thanks in advance.

Regards,
Noel Milton Vega

Yes.  

Assuming this is a panic from the Solaris kernel:
In the GRUB menu, edit the "Solaris xVM" boot entry,
append options " -kv" at the end of the
"module$ /platform/i86xpv/kernel/$ISADIR/unix
/platform/i86xpv/kernel/$ISADIR/unix"
line, and boot the modified xVM entry.  Now the system
should stop in the kernel debugger if we do get a kernel
panic.  Before it stops in the debugger, a panic message
is printed, cpu registers are dumped and a stack backtrace
is printed.

Instead of using kernel options "-kv" you can also try
"-kdv".
In this case it stops in the debugger before starting the Solaris
kernel. To start the kernel use the kmdb command "::cont"
(or ":c")
