All that you'll get > with basic LVM is the ability to resize one guest down and another guest up. I pointed /dev/VolGroup00/myguest within virt-manager and installed the guest. Suppose that I need to add an extra physical disk or instead of borrow, only resize one guest down and another guest up. I did a lvextend to add 1G to myguest, but how can I make my guest see that change? In lvm How To they use the command resize2fs to resize the filesystem, but I do not realize how to apply that changes to guests using LVM or partitioned by the guest installer. I tried to use the guest drive partitioned as /dev/xvda1 (boot), /dev/xvda2 (/) and /dev/xvda3 (/home) and also with LVM. How can I make the guest see that change? Thanks!
