Hello All,
We would appreciate your advice on the following issue.
We have created a full virtualized Xen guest that its disk is an image file
of 4GB.
We want to use this image file as a template for creating Xen guests which
their disk will be an LVM device.
The disk image file is of type:
file /var/lib/xen/images/rhel52.img
/var/lib/xen/images/rhel52.img: x86 boot sector; partition 1:
ID=0x83, active, starthead 1, startsector 63, 9221247 sectors;
partition 2: ID=0x83, starthead 0, startsector 9221310, 19438650
sectors, code offset 0x48
By dd/cat this image file to an empty LVM device
cat /var/lib/xen/images/rhel52.img > /dev/VolGroup00/rhel52
and by using this configuration file
name = "rhel52"
uuid = "b8ba7d42-191c-3ab9-5f78-40d1c1f1ab67"
maxmem = 2048
memory = 2048
vcpus = 1
builder = "hvm"
kernel = "/usr/lib/xen/boot/hvmloader"
boot = "c"
pae = 1
acpi = 1
apic = 1
localtime = 0
on_poweroff = "destroy"
on_reboot = "restart"
on_crash = "restart"
device_model = "/usr/lib/xen/bin/qemu-dm"
sdl = 0
vnc = 1
vncunused = 1
keymap = "en-us"
disk = [ "phy:/dev/VolGroup00/rhel52,hda,w" ]
vif = [ "mac=00:16:3e:36:b5:50,bridge=xenbr0" ]
serial = "pty"
we can boot the machine and everything is working properly.
We want to be able to provide the flexibility to enlarge partition number 1
size to the size of the LVM device.
Please note that we are not aware of the LVM device size in advance, that's
why we need this flexibility.
For example our LVM size is 20GB and our image file is just 4GB.
How can we adjust the partition size ( 4GB in our case ) to the LVM size
( 20GB in our case ) ?
If there is a better way to accomplish this task we would also be happy to
know.
Thanks,
Ido & Alexandra
