<br>Hello, typically my kvm guest disk is <br><br>/dev/sda1 /boot<br>/dev/sda2 logical volume group<br><br>inside sda2 are two LV partitions<br>/<br>swap<br><br>Don't know if that answered your question. Remember that to enlarge a LV group, you need another device like /dev/sda3 to merge with that volume.<br><br><br>----------------------------------------------------<br><b><br>Charles T.

When<br>> installing a guest operating system is it advisable to place each<br>> instance in a separate lv or better to accept the default and store<br>> them on the root file system?<br>> <br>> Respecting lvm, does one configure lvs in a virtual server to take<br>> space from the main vg or does one allocate lv space from inside<br>> that allocated to the virtual instance? Is it even considered<br>> advisable to use lvs with virtual guests?<br>> <br>> To give an example, if I were to configure an smtp server on bare<br>> metal I might use the following disk layout:<br>> <br>> vg_bare 500Gb<br>> <br>> / lv_root 8Gb<br>> /boot lv_boot 1Gb<br>> /tmp lv_tmp 8Gb<br>> /var/log lv_log 8Gb<br>> /var/spool/mail lv_mail 16Gb<br>> <br>> <br>> In a kvm setup, if I wish to do this, would I first create an lv<br>> just to host the virtual image and then assign lv s from the space<br>> allocated to that image file?<br>> <br>> vg_bare 500Gb<br>> <br>> / lv_root 8Gb<br>> /boot lv_boot 1Gb<br>> /tmp lv_tmp 8Gb<br>> /var/log lv_log 8G<br>> <br>> /var/lib/libvirt/images/lv_virt01 32Gb<br>> /var/lib/libvirt/images/lv_virt02 32Gb<br>> . . .<br>> <br>> and so forth? Or is it worth the bother to have lv s in a virtual<br>> host?<br>> <br>> -- <br>> *** E-Mail is NOT a SECURE channel ***<br>> James B.
