Dear All,
I am sorry for this post if at all i used the wrong forum but I guess someone out there will be there to advise me and help me out and would be really apprecite and be grateful i have new to xen and has setup my first virtual machine
I have a centos 5.5 xen server working perfect and have installed a virtual 2008 server and its working fine . Actually i created the virtual machine in manager installation wizard with the following option. in the storage option I selected File (disk Image) the location /var/lib/xen/images/image.img ( I have about 400gb free in /var partition) size i choose 15000 mb deselect the checkbox ... allocate entire virtual disk now
since the below warning says
if you dont allocate the entire disk now , space will be allocated as needed while the virtual machine is running .
The 2008 server was installed perfect. and also I did install some software and c drive showed me 800 mb free
now I tried to copy 1 gb file to my virtual machine and it said I dont have space .
Now I was thinking that additional space would be allocated on the fly as the note says above
i am just wondering why its not allocating more space or what would be the ideal way now for allocating more space
if I wanna create a new virtual machine choosing the block device( partition option) is the correct way to avoid this problem??
I actually would like the virtual machine to use as much as it requires as long as there is free space on my local disk
apprecite your kinfd advice and help
regards simon

This appears to be the issue. When I install Windows it shows the full size I've specified, not the size of the allocated file. It's somewhat possible, though unlikely, that Windows has used up 15G for the installation. Windows creates a page file and miscellaneous backups. Also, there is some overhead when creating the filesystem. Have you gone into the disk manager and verified that all of the volume is being used?
now I tried to copy 1 gb file to my virtual machine and it said I dont have space .

15GB is way too low for server2008, take 60gb at least (don't know what you want to do with it). Your server is allocating space untill the 15GB you gave it. It is a max.
if I wanna create a new virtual machine choosing the block device( partition option) is the correct way to avoid this problem??

Give it more than needed, and let xen do the allocating (as you have set).

Dear Guys,
Thanks and really appreciate you kind and immediate replies actually i am quite a novice in virtual machines and as usual after some reading went through the wizard in virt manager
Now when it comes to the page for specifying the disk space i see the following as warning (if you don't allocate the entire disk now , space will be allocated as needed while the virtual machine is running)
Now as per the message i was thinking that I would just give the minimum space for the OS and xen would allocate space as I install software and put data and files as required So guess basically I was wrong in interpreting the message Now I began to understand and as leen says .. the space specified in the wizard is the maximum and Xen in no way will allocate more space than specified in the wizard so it above message basically means that space is allocated and managed by xen within the maximum space specified in tghe wizard. I hope i am right with the above
so I gonna delete the virtual machine and create a new one since I have about 400gb and plan to have 2 virtual machines
apprecite if you share your views
thanks and regards
simon

The virtual disk works just like a hard drive. If you create a 80GB hard drive it reports it to the guest OS as a 80GB hard drive. The "don't allocate the entire disk now" message is about how the host OS creates the virtual disk file. If you don't allocate it up front you end up with a sparse file. du and df commands will show the space actually used. ls will show you the actual file size which would be 80GB.
