According to Xen wiki page, graphic subsystem is not working with 2.6.38 [1], so I disable GDM. I also set up various Xen and Linux debug options, now that my grub entry looks like: --- start of grub config --- multiboot /boot/xen-4.gz com1=115200,8n1 console=com1,vga sync_console console_to_ring loglvl=all guest_loglvl=all noreboot lapic=debug apic_verbosity=debug apic=debug iommu=off module /boot/vmlinuz-2.6.38.4-liuw+ console=hvc0,vga earlyprintk=xen nomodeset initcall_debug debug loglevel=10 root=UUID=fd49322b-830f-44d2-8bdf-de5c355bb159 ro quiet --- end of grub config --- Another thing I do is setup a serial tty in /etc/inittab, which looks like: --- start of inittab --- s0:2345:respawn:/sbin/getty 115200 ttyS0 --- end of inittab --- After Xen relinquishes the VGA console, the screen goes black. Serial line has some output, but no login prompt is showed. However, I can login with SSH. Everything works fine. So it seems that the VGA console and serial console are not working properly. Any suggestions? [1] http://wiki.xensource.com/xenwiki/XenPVOPSDRM -- Best regards Wei Liu Twitter: @iliuw Site: http://liuw.name
