Re: [Xen-devel] Kernel DomU 2.6.36-rc6-pvhvm dont boot PVonHVM

[Roberto Scudeller <beto.rvs@xxxxxxxxx>]

Hi Stefano,

This is my DomU.cfg:
kernel='/usr/lib/xen/boot/hvmloader'
builder='hvm'
memory=512
vcpus=2
pae=1
acpi=1
apic=1
vif=['bridge=virtbr']
disk=[ 
'tap2:tapdisk:vhd:/PATH/ubuntufv/hda.vhd,hda,w', 
'tap2:tapdisk:vhd:/PATH/ubuntufv/hdb.vhd,hdb,w', 
]
device_model='/usr/lib/xen/bin/qemu-dm'
boot='c'
sdl=0
vnc=1
vncunused=1
stdvga=0
extra=''
>
>ramdisk=''
image_name='ubuntufv'
>bootloader=''
root=''
platform='xen'
network_mode='tap'
usb = 1
usbdevice = 'tablet'


Any ideas??


Thanks for your help.


Cheers,

these are ment for pure PV guests and shouldn't be used with an HVM

Can you please post your entire DomU.cfg?
