to be honest i am not sure of the above method.. all i did was create a logical volume using lvm for each guest the size i wanted that guest to have. easy to extend if more space is needed for a given guest. i followed this how-to below but interpolated my own needs into it and it worked great the first time out. now each guest is limited to a 10g 'hdd'. on my next round of installs some will be a 40g etc...and it doesn't place any extra responsibility on the kernel for quotas or anything. http://www.gentoo.org/doc/en/lvm2.xml although the doc is written for gentoo, the information in it is not gentoo specific besides how to install packages. the only other change i made was i did not use modules but included all lvm items needed within the kernel since i use monolithic kernels (not capable of loading modules). i used one volume which was half the raid disk system i have set aside for this, leaving the other half to be used sometime in the future as needed. i then used the file system i wanted for each guest on each virtual volume. i made a small /vservers "home" mount point and then mounted the individual guest disks within that so it is all well separated from the host. the final tree looks like this now with each volume/mount point the name of the guest: /dev/sda6 9.4G 516M 8.9G 6% /vservers /dev/mapper/vg-colossus 10G 429M 9.6G 5% /vservers/colossus /dev/mapper/vg-nagios 10G 371M 9.7G 4% /vservers/nagios /dev/mapper/vg-ns 10G 352M 9.7G 4% /vservers/ns /dev/mapper/vg-ns1 10G 342M 9.7G 4% /vservers/ns1 /dev/mapper/vg-ns2 10G 337M 9.7G 4% /vservers/ns2 /dev/mapper/vg-prometheus10G 703M 9.4G 7% /vservers/prometheus /dev/mapper/vg-usage 10G 528M 9.5G 6% /vservers/usage that's about as close to physically partitioning the disk for each as you can get but any of them are easily extendable and won't pass its own boundaries if a rogue guest gets artistic and desides to write pretty 1 and 0 designs all over the 'disk'. :) . this was my first attempt with lvm and i honestly now cannot say how i lived without it before. :) > And how LVM could assist in limiting disk space of each guest server?
