[Xen-users] HVM vs PV - conversion

[fpt stl <fptstl@xxxxxxxxx>]

Greetings,

I would like to know how one can identify if a DomU is PV or HVM? Any docs which may indicate a way to find out?

I have a CentOS 5.5 64bit DomU which might be HVM - how can this DomU can be made PV?

Just stop the DomU, and then delete it using Virtual Machine Manager and the create another config file for a PV DomU and use xm new and then xm start?

Let's say I have a config file like: [for a HVM DomU]

VMHOST1 /]# more /etc/xen/DBS1

name = "DBS1"

uuid = "904ec14c-9a46-3dae-ee7a-16470c5f5ef5"

maxmem = 4096

memory = 2048

vcpus = 2

builder = "hvm"

kernel = "/usr/lib/xen/boot/hvmloader"

boot = "c"

pae = 1

acpi = 1

apic = 1

localtime = 0

device_model = "/usr/lib64/xen/bin/qemu-dm"

sdl = 0

vnc = 1

vncunused = 0

vncdisplay = 53290

keymap = "en-us"

disk = [ "phy:/dev/VG1/DBS1,hda,w" , "phy:/dev/VG2/DBR,hdb,w", "phy:/dev/VG2/DBR_backup,hdc,w" ]

vif = [ "mac=00:16:36:0a:aa:69,bridge=eth4,script=vif-bridge" ]

parallel = "none"

serial = "pty"

Just changing the config file to something like:

VMHOST1 /]# more /etc/xen/DBS2a

name = "DBS2a"

maxmem = 4096

memory = 2048

vcpus = 2

cpus = "1-7"

bootloader = "/usr/bin/pygrub"

vfb = [ "type=vnc,vncunused=1,keymap=en-us" ]

disk = [ "phy:/dev/VG1/DBS2a,xvda,w" , "phy:/dev/VG2/DBR2,xvdb,w" , "phy:/dev/VG2/DBR2_backup,xvdc,w" ]

vif = [ "mac= 00:16:36:0a:aa:69,bridge=eth4" ]

will create a PV DomU? [xm new DBS2a , xm start DBS2a]

Is it a way to convert a config.sxp into a "xm" config file like the one above?

Thank you for your help!

Frank
