How can a lvm based xen was mor quickly an a image based I have just convert my images to lvm thanks to luke for all info _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I''m about to install a whole bunch of DomUs, each with a different
operating system.
It''s definitely faster not to use a file-backed block device. LVM is
more flexible than partitions, and partitions are somewhat tedious (and
dangerous) to set up.
Is there any *measurable* overhead of using LVM as opposed to simple
partitions?
The two concerns I have are, how quickly can the physical disk sector
number be calculated given the sector offsite in the device (either
partition or LVM), and whether LVMs can be made physically contiguous.
