Hi,

That works for me too.


Thank you

For 8.1 you must build your kernel without the keyboard drivers for
the time being.  This issue is pretty well documented at this point,
so you should be able to find the instructions pretty readily.

I've done this and it doesn't seem to hurt anything (the Xen "serial
console" for the machine still works fine).

FreebBSD 8.1-STABLE i386 PV DomU kernel panic at HYPERVISOR_update_va_mapping

2010-10-22 Thread Yuriy Kohut 
Hi,

I have installed FreeBSD 8.1-STABLE paravirtualized Xen DomU according to the 
documentation at:
http://forums.freebsd.org/showthread.php?t=10268

RELENG_8 CVS tag was used to get world and kernel sources.

The kernel get into panic while booting:

panic: HYPERVISOR_update_va_mapping(((unsigned long)(va)), (pa | 0x002 | 0x001 
| pgeflag | pmap_cache_bits(mode, 0)), UVMF_INVLPG| UVMF_ALL) < 0:

DomU built from RELENG_8_0 booted fine for me. But it is very unstable. Kernel 
panics every time DomU is more higher loaded with network, CPU or memory. I 
reported several BRs for them, but with no result for the moment.


Could somebody please assist with the panic ?
