Dom0 ubuntu 12.04
domu 12.04
xen 4.2.1

hvm works well for base img,
but could not access to a qcow img based on base img.


log:

Unknown PV product 3 loaded in guest
PV driver build 1
region type 0 at [f3000000,f3020000).
squash iomem [f3000000, f3020000).
region type 1 at [c100,c140).


cfg:

disk = [ 'tap:qcow:/var/station1/vmdisk-station1.qcow,ioemu:sda1,w' ]

the disk type of domu is xvda, I could not only get this type for creating
a unbunt hvm.


vmdisk-station1.qcow is created by
qemu-img-xen create -b vmdisk.img -f qcow vmdisk-station1.qcow




screen information :

ata0 master : qemu harddisk ata-7 hard-disk


c900 pci2.10 pmm+00100010+00111020 c900

booting from hard disk


it looks the new hvm could not find the entry address of hard disk, but I
do not know how to fix

I would be very grateful if anyone give any information, thank you.

Maybe have a look at various xl config file examples in /etc/xen? The
syntax you used looks out-dated to me.
