needs to be a custom script specific to the particular guest OS, I suppose.
something like "lvresize --resizefs …" 
Maybe some rescan of partitions (if the missing piece is indeed the missing 
qemu-ga notification) - then just force it with fdisk

Re: [ovirt-users] VM Deployment By Template

[Punit Dambiwal]

Hi Ovirt&KVM,

Here is the details :-
1. Ovirt :- 3.4
2. VM :- Centos 6.5
3. VM Disk Partition :- Based on LVM
4. Base Datastorage :- Gluster

I am able to expend the disk...but the disk expand doesn't touch the
partition table..so after expand all the existing partition remain with the
same disk sizenow i need to manually create another partition and add
it in to Volgroup and resize the logical volume...

Thanks,
Punit

Re: [ovirt-users] VM Deployment By Template

[OvirtAndKvm]

Punit,

What file system is your VM's partition, what operating system and
version ?

A question to others, if the doco says "we support "disk resize" since
3.4", for what virtual disk type, and which operating systems and
their partition types are supported by this.  I would have believed
you would needed to have used LVM and then add the new disk space as a
new LUN, and map the new lun, while also using a file system that
allows for expansion. Some file systems like XFS can be extended (i.e.
grow) while being mounted. This is about the limit of my knowledge so
if you know more, please let us know what is possible.

provisioning.

http://www.gnu.org/software/parted/manual/html_node/parted_31.html
Grow partition 1, into the adjacent free space: 

(parted) resize 1 0.063
874.9http://geekpeek.net/resize-filesystem-fdisk-resize2fs/
http://www.linuxuser.co.uk/features/resize-your-disks-on-the-fly-with-lvm

http://docs.oracle.com/cd/E37670_01/E37355/html/ol_grow_xfs.html
You can use the xfs_growfs command to increase the size of a mounted
XFS file system if there is space on the underlying devices to
accommodate the change.

http://www.ovirt.org/Features/Online_Virtual_Drive_Resize
Features/Online Virtual Drive Resize 
QEMU-GA 

*  support for notifying the guest and updating the size of the
visible disk: [Yet?] To be integrated 
http://serverfault.com/questions/122042/kvm-online-disk-resize 
AFAIK, this is not possible -- you can add new disk images, and as you
point out you could also add new images to an LVM volume, but in order
to resize an active, bootable disk image you need to be able to shut
it down and edit the partitions.

It is possible to move a Linux system between disks while it's
running. The limitation is that you cannot alter partitions on a disk
that has partitions in use.



To do this your root filesystem must be on an LVM, this often means
that you have to have a separate boot filesystem (this is not,
however, essential, it just makes things easier)

You may be able to do that with cloud-init custom-script section,
The following link will show you how to add a file to the client, you
may write a code
that change the partition table, you need to make the file executable
and put
it in a init section (such as /etc/init.d sections), the only problem
is that
it may be too late since cloud-init may be loaded after that phase...
(so
maybe other place...)

Another option is to set a command under this section:

You may be able to do that with cloud-init custom-script section,
The following link will show you how to add a file to the client, you may write 
a code
that change the partition table, you need to make the file executable and put
it in a init section (such as /etc/init.d sections), the only problem is that
it may be too late since cloud-init may be loaded after that phase... (so
maybe other place...)
http://cloudinit.readthedocs.org/en/latest/topics/examples.html#writing-out-arbitrary-files

Another option is to set a command under this section:
http://cloudinit.readthedocs.org/en/latest/topics/examples.html#run-commands-on-first-boot

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?

Re: [ovirt-users] VM Deployment By Template

[Punit Dambiwal]

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 samethen 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...

Is the cloud-init...custom script can do this or not ??

Thanks,
Punit

 so you want to provision a VM with a different disk size

 good point. some thoughts:
 1. for thinly provisioned (qcow2) - its COW, hence the same

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.

 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

 I probably don't understand what are you trying to achieve.

Hi Itamar,

Thanks for the updateYes.. 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

Re: [ovirt-users] VM Deployment By Template

[Punit Dambiwal]

Hi Sven,

It's Ok...but still the drawback is if i have 100GB template and use clone
instead of thinnow if i want to create 10 VM with this template...it
will copy 1TB data...and the provisioning will take long time ??

Is there any other work around to make this copy partial or the ovirt just
copy the actual used data at the time VM deployment instead of the whole
virtual disk

Otherwise it's very hard to use Ovirt as public cloud...because if every
time it copy the whole template...and simultaneous more then 10 process
running for the VM deployment all the process will stuck..

Another way i got is create the VM with 1GB virtual template and expand the
disk size after deployment...but the problem here is disk will expand...but
it will not done any changes in the existing partition table..that means
after expand disk you need to manual login in to server and make the
changes with the help of fdisk and lvm commands...

Seems Ovirt is not proposed for the public cloud ??

Thanks,
Punit

If you have a "thin" template and create a new vm using the option:
"clone" what ovirt does is copy the thin template to a new disk.
when you use "thin" ovirt does not create a new disk for the vm, instead
the new vm shares the thin disk with the template (same file!)
and creates another file just for the differences between template
and vm, which accumulate over time.

notice that you can not delete a template which has thin provisioned
vms depending on it unless you delete all those vms.

Re: [ovirt-users] VM Deployment By Template

[Darren Hart]

So you essentially want to just deploy a new VM based on a template with a thin 
provisioned disk ?

When you create your VM based on the template check in advanced options – 
Resource allocation and see if the option there for template provisioning is 
set to clone or to thin provision. Clone in your case I believe would create a 
40GB image file based on the template whereas thin provision will create you a 
thin provisioned disk just using the same actual data amount as the thin 
provisioned template. I’m pretty sure you can only do this if your template 
disk is thin (not preallocated) provisioned.

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) diskit will copy 
the whole 40GB to provision the virtual machineso 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 sizeand 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.. ??

Thanks,

Re: [ovirt-users] VM Deployment By Template

[Punit Dambiwal]

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) diskit will
copy the whole 40GB to provision the virtual machineso 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 sizeand 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.. ??

Thanks,
Punit

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

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?

Re: [ovirt-users] VM Deployment By Template

[Punit Dambiwal]

Hi Michal,

2. I find disk size can not modify at the time of VM provisioning,is there
any way to modify the VM disk size ??

well, not really, AFAIK.
create another disk, move your data, remove the original Or create a bigger
thin provisioned disk at the beginning...

I didn't understand the mean...i can create the another disk...it's
ok...but how to move the data from the existing disk to new disk at the
time of the VM deployment... ?? is there any way to move the data.. ??

Another question is there any way to mount the img like 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...

Thanks,
Punit

if you deploy with thin provisioned disks it should be 1GB

well, not really, AFAIK. 
create another disk, move your data, remove the original.
Or create a bigger thin provisioned disk at the beginning

Hi All,

I have some questions regarding the VM deployment through OS template...

1. I have imported centos template from openstack glance (the actual size
of the template is 16GB but used is 1GB)...now my question is if i deploy
the new VM with this template,the process will copy the whole 16GB or just
1 GB to create the new VM ??

2. I find disk size can not modify at the time of VM provisioning,is there
any way to modify the VM disk size ??

Thanks,
Punit
