Hello,

i had no luck in booting 32bit PAE pv_ops dom0 on xen-3.4-unstable so far...
Booting the bzImage on bare Metal works like a charm (it's even stable under high load), but booting the vmlinux over xen gives just a jump of the cursor to the top left corner after the last messages from the hypervisor. My Test-Box (Dell XPS-720) lacks a serial port so i can't check if it's just a vga issue.

I have most xen related options configured as modules maybe that might be the problem. I'll try to check that out over the next week.

Next thing i'll try is to use xen-3.3.1 hypervisor to check that it's not hypervisor related. I also try to dig out some older Boxes on which 3.3.1 runs at the moment and try if it actually prints something to a serial console...


VGA console is not currently working in pv_ops dom0 patches. At least I
haven't figured out how to make it work.

Serial console works for me.
There seems to be some problems with IRQ routing (?).. and thus ahci and 
ata_piix
drivers don't seem to work currently.
Hopefully next week we can get some debugging done when Jeremy is back.

Hello Pasi,

followed the discussions about that and was sad to read that as my boxes here also use the ata_piix module to get the root device. I'll try to build a x86_64 image tomorrow as is think it's a PAE problem.
Can you send me your working kernel config file?

I also got another hickup here. On 3 other Boxes i tested on i get an instant reboot after the dom0 builder executes the pv_ops vmlinuz image... i think it panics pretty close after execution on 32bit PAE... I have to dig out a serial cable to put some boxes together to capture some logs. I'll post them when i get there.
