Hi all, I am new in virtualization so forgive me any evidence. After pool definition, when I try to create a logical pool I obtain the following error: <blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote"> <div style="margin-left: 40px;"># virsh pool-define vms.pool.xml Pool vms.pool defined from vms.pool.xml # virsh pool-start vms.pool error: Failed to start pool vms.pool error: internal error '/sbin/vgchange -ay vms.pool' exited with non-zero status 5 and signal 0: Volume group "vms.pool" not found </div></blockquote> Is anything wrong with my xml file? <blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote"><div style="margin-left: 40px;"> <pool type="logical"> <name>vms.pool</name> </div></blockquote><blockquote style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;" class="gmail_quote"> <div style="margin-left: 40px;"> <source> <device path="/dev/sda2"/> </source> <target> <path>/var/lib/virt/images</path> </target> </pool> </div></blockquote> Are pools created in this way permanent? Thank you! Jenaro Percal
