[libvirt-users] Pool, iSCSI and guest start

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Former user of Xen and newbie in kvm/qemu/libvirt stuff, I give it a try on my network ;-) I need to run a VM with iSCSI target attached. I did it this way : 1) Creation of iscsi pool (equa.xml) : <pool type="iscsi"> <name>equalog</name> <source> <host name="10.10.0.1"/> <device path="iqn.2001-05.com.equallogic:0-8a0906-4992c7f05-39c000000114b8fc-vglog"/> </source> <target> <path>/dev/disk/by-path</path> </target> </pool> This pool start smoothly (when open-iscsi started), no problems. An entry is created in /dev/disk/by-path/ related to iscsi target. 2) I flagged it autostart : root@sandi:~# virsh pool-autostart equalog Pool equalog marked as autostarted root@sandi:~# virsh pool-list Name State Autostart - ----------------------------------------- equalog active yes 3) In my guest VM, I have following section : <disk type='block' device='disk'> <driver name='qemu'/> <source dev='/dev/disk/by-path/ip-10.10.0.1:3260-iscsi-iqn.2001-05.com.equallogic:0-8a0906-4992c7f05-39c000000114b8fc-vglog-lun-0'/> <target dev='vdc' bus='virtio'/> <alias name='virtio2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </disk> When I start VM, iscsi target is availaible. The snag is that when I reboot the host, the pool is not automatically started (making it impossible to autostart VM relying on this iscsi volume). I verified that open-iscsi is started first. Startup script is localised in /etc/rcS.d which is prior to /etc/rc2.d (my default runlevel). Libvirtd is started in rc2.d and not mentionned in rcS.d. My questions are : - - Is this the correct way to attach iscsi volume to a guest ? - - Did I missed something to have iscsi pool autostart working at boot time ?
