Hi, guys. I''m trying to use physical disks as virtual disks in HVM domains. But I couldn''t. I''m using cs10508 of xen-unstable.hg. When I use disk = [ ''phy:sda5,ioemu:hda,w'' ] in conf file, creating HVM domain says, I need to use ''file'' modifier if I use ''ioemu''. So, I changed it to disk = [ ''phy:sda5,hda,w'' ]. But HVM window doesn''t pop up. Did you guys solve this problem? Can''t I use physical disk partitions for virtual disks? Thank you in advance. -- 장재완 드림 Jae-Wan Jang jwjang@camars.kaist.ac.kr +82-42-869-3559 http://camars.kaist.ac.kr/~jwjang _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Did you install OS into sda5? Could you mount /dev/sda5 in domain0? I can use physical partitions as virtual disks. There are two ways to use a physical partition as virtual disk. One way: Native and VMX share the same MBR on /dev/sda. And the guest root fs is a partition of domain0. You can mount /dev/sda5 directly in domain0. mount /dev/sda5 /mnt/ Another way: VMX has created its own MBR in /dev/sda5. To mount the guest root fs you have to add an offset. mount -o offset=32256 /dev/sda5 /mnt/ With the 1th way You should use disk = [ ''phy:sda,ioemu:hda,w'' ] And the grub on sda should have a grub entry for hvm.

I use the following and it works fine in Windows (native, VTX enabled), I
see the LVM that I'm passing as a raw hard disk, which I formatted and
continue to use.
builder='hvm'
memory = '384'
name = "win2k31"
vcpus=1
pae=0
acpi=0
apic=0
cpus = ""
vif = [ 'type=ioemu, bridge=xenbr0',
'type=ioemu, bridge=xenbr1' ]
disk = [ 'file:/root/windisk/win2k31.img,ioemu:hda,w',
'phy:/dev/sda3,ioemu:hdb,w' ]
on_poweroff = 'destroy'
on_reboot = 'destroy'
on_crash = 'destroy'
device_model = '/usr/lib/xen/bin/qemu-dm'
cdrom='/root/windisk/win2k31.iso'
boot='c'
sdl=1
vnc=0
vncviewer=0
stdvga=0
serial='pty'
ne2000=0
