Hi everyone,

I was trying to build a new machine but the system keeps rebooting.
I used the lasted unstable version from xen-unstable.hg.

I have tried with Fedora 16 (kernel 3.3.0-8) and Xubuntu 11.10 

The output to my serial console is attached.

What is your Linux command line? does it include "console=hvc0"?
Perhaps some early_printk settings are required.

Please include my email in your replies, thank you.

Yes, it includes hvc0. I used your tutorial to setup the SOL.

title        Xen 3.4.2 / pv_ops Linux dom0 with a serial console
root         (hd0,0)
kernel       /xen-3.4.gz dom0_mem=512M loglvl=all guest_loglvl=all sync_console 
console_to_ring com1=115200,8n1,0xe000,0 console=com1
module       /vmlinuz- ro root=/dev/vg00/lv01 console=hvc0 
earlyprintk=xen nomodeset
module       /initrd-

Something like this, I am not at the machine anymore.


It looks like xsave/xrstore instructions (xsetbv instruction in xstate_enable() function to be exact) related. You can try to disable xsave to to see if this helps.
