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 -------------- next part -------------- An HTML attachment was scrubbed...
