Hi!
I run in one occasion for experimenting and learning purposes OpenBSD
under 64 bit Debian Lenny dom0 on Intel-VT capable hardware (Intel
DP35DP motherboard). OpenBSD is i386 HVM domU (it was patched 4.4 stable
for a while and then i replaced it with current from Jan 19) and it
essentially works all right except network is 10 MBit/s and in OpenBSD
it gives a lot of messages like that
Mar 18 21:18:14 t2a /bsd: ne5: length does not match next packet pointer
Mar 18 21:18:14 t2a /bsd: ne5: len b201 nlen 6001 start 4c first 6b curr
71 next cc stop 80
Mar 18 21:18:14 t2a /bsd: ne5: NIC memory corrupt - invalid packet
length 24577
Here is my domU configuration
kernel = '/usr/lib/xen-3.2-1/boot/hvmloader'
device_model = "/usr/lib/xen-3.2-1/bin/qemu-dm"
builder = 'hvm'
memory = '256'
disk = [ 'phy:/dev/data/openbsd_44_current_20090121_i386_2a,ioemu:hda,w', \
'phy:/dev/loop2,ioemu:hdc:cdrom,w']
name = 'openbsd_44_current_20090121_i386_2a'
vif = [ 'mac=70:01:68:01:02:54,bridge=xenbr0,model=ne2k_pci', \
'mac=70:01:68:00:12:54,bridge=xenbr1,model=ne2k_pci', \
'mac=70:00:00:00:12:54,bridge=xenbr2,model=ne2k_pci', \
'mac=70:00:16:01:00:01,bridge=xenbr3,model=ne2k_pci', \
'mac=70:00:50:09:61:38,bridge=xenbr4,model=ne2k_pci', \
'mac=70:00:10:10:02:54,bridge=xenbr6,model=ne2k_pci', \
'mac=70:00:16:02:02:54,bridge=xenbr5,model=ne2k_pci' ]
cdrom="/dev/hdc"
boot='c' #d is cdrom boot, c is disk boot.
vnc="1"
vncviewer="1"
sdl="0"
vcpus=1
acpi=0
on_poweroff = 'destroy'
on_reboot = 'destroy'
on_crash = 'destroy'
I fancyied to delegate network adapters to the HVM with PCI-passthru to
make my problems go but got an impression that on my hardware it is not
possible since it doesnt have IOMMU. (Actually passthru works for PV
domU's).
I would be very thankful if you could share a bit more of your
experience and i could get rid of network speed limit and these messages
in logs.
Best regards,
Imre

what virtualization you use (vmware , openvz , etc )?
Hello,
Using Xen myself (debian packages). Got one dom0 on Debian 64bits and
the domU is an OpenBSD 4.4. Technology using HVM too.
Cheers,
