How to refresh lvm-backed virtual disk in libvirt
How can I grow a libvirtd VM's LVM-backed virtual disk online, without rebooting the vm. My host has an LVM VG for VMs. Each VM disk is an LV to the host. It's easy to grow the VG by adding a PV and extending the LV. But the VM doesn't "see" the new space without rebooting. How can I get the VM to see the larger space without rebooting the VM?
