Hi Itamar,
It's the same as i used and discussed in last reply...create the VM
with 1GB virtual template and expand the disk size after
deployment...but the problem here is disk will expand or resize...but
it will not make any changes in the existing partition table..that
means after expand disk all the existing partition will remain
same....then you need to manual login in to server and make the
changes with the help of fdisk and lvm commands..
I am looking for the way we can resize the disk...and at the same time
when the disk will expand...it should be resize the partition table...
I think this is what you were after:
"QEMU-GA
support for notifying the guest and updating the size of the visible
disk: To be integrated "
So maybe you could post an RFE on that for "qemu-ga"? Help testing?
/K
Is the cloud-init...custom script can do this or not ??
Thanks,

Hi Itamar,
To edit the disk size are you referring this "Another
way i got is

done any changes in the existing partition table..that

Or it's different then the upper one...please let me
know how to perform
this...if any screen shot you can provide for better
understanding..

Hi Itamar,
Thanks for the update....Yes.. i want to
create different size
VM with
the same OS template...
------------
3. we support "disk resize" since 3.4 (iirc),
which you can do
post VM
provisioning.
considering #3, then #1 should be easy to
support as well these
days.
please open an RFE.
------------
Could you please more elaborate point number
3...how to use
it..i will
go with this one ...
iirc, you just need to edit the disk size when vm
is down or up (for
up, only for specific disk interfaces, virtio-blk,
not ide, iirc)
Thanks,

Hi Michal,
I want to deploy the VM with the
template but the
problem is in
ovirt
when you deploy the VM by template it
copy the whole
image(even
thin or
thick disk)...like if i have 40GB
virtual size (actual
size 1GB)
disk....it will copy the whole 40GB
to provision the
virtual
machine....so if i want to deploy 10
VM simultaneous
then it
will copy
4TB data and take long time to
provision....
I want the way i can make the
template with small
size....and once i
choose to create the virtual machine
with 40GB...the VM
deploy
with the
small template on the 40GB disk... is
it possible with
ovirt.. ??
so you want to provision a VM with a
different disk size
than template.
good point. some thoughts:
1. for thinly provisioned (qcow2) - its
COW, hence the same
size.
2. for clone - actually, no reason
shouldn't be supported
easily.
3. we support "disk resize" since 3.4
(iirc), which you can
do post
VM provisioning.
considering #3, then #1 should be easy to
support as well these
days. please open an RFE.
Thanks,

Hi,
You would have to do that inside
the guest…the
same way as
you would
do it on real hardware…mount
both disks, move the
relevant data
not trivial and not automated

way to mount the

i will
create the VM with blank
template with my
preferred disk
size and
leter on install the OS through
any OS template
??? i know
i can
install the OS through CD-ISO
but i don't want the
manual
installation…
so you want to have a
preinstalled OS…so how did
you want
to use it?
I probably don't understand what
are you trying to
achieve.
Anything else than having a
Template with OS and
you deploy
VMs from
that….you need to change disk
sizes for each such
VM? Could
it be
done by adding an additional
disk?
