Well I could not wait until 3.1.0. I want to attach an usb device too an
guest by passing through the whole usb bus. I have seen it work in
2.6.32.4(something). On rc4 it almost works:
Xen: version 4.1.1
dom0: kernel 3.1.0-rc4+
guest: kernel 3.0.0
pure pv by lac off hvm capable hardware
grub:
...
multiboot /xen-4.1.1.gz dom0_mem=512M dom0_max_vcpus=1 loglvl=all
guest_loglvl=all com1=115200,8n1 console=com1,vga
module /vmlinuz-3.1.0-rc4 root=/dev/md2 ro console=hvc0 earlyprintk=xen
xen-pciback.hide=(00:1d.0)(00:1d.1)(00:1d.2)(00:1d.7)
pci=resource_alignment=00:1d.0\;00:1d.1\;00:1d.2\;00:1d.7
Only 00:1d.7 was complaining about "non-page-aligned MMIO BAR" so
aligning the other three is overdone?
guest boot:
