Unable to add Storage Pool in Virtual Machine Management GUI tool

Mark_667 · 01-16-2012, 10:37 AM

I'm having some difficulty with the Virtual Machine Management GUI tool on SLES 11 SP1, the storage pool pointed to a location under /var by default. I couldn't see how to change it so I deleted it and now get the message 'Libvirt connection does not support storage management'. The Virtual Networks and Network Interfaces tabs give similar messages. When I try to add a Storage Pool I get:

try to create your storage under /var/lib/libvirt/images or just under /var/lib/libvirt/ because if selinux is enabled on enforce mode is going to preventing you from create storage on other dir or else you can change the boolean of the dir

/var is on the root partition and there isn't enough space for the disk images on there-any ideas?

you can create on any dir and label that dir with virt_image_t boolean type.
and you can also use virsh pool-edit default to edit your default storage pool and edit the xml file under path section and put your new dir there

Thanks for the tip, it put me onto this:

Code:

virsh pool-dumpxml default > pool.xml
edit pool.xml # with new name and path
virsh pool-create pool.xml
virsh pool-refresh name

Unfortunately they don't seem to be very comprehensive-they don't mention that you need to be root to make the changes or what to do with the UUID in the XML file. Leaving it unmodified gives an error saying that the storage pool already exists. Modifying it slightly gives another error:

Quote:

error: cannot open volume '/home/me/.gvfs'

Even when running the command after suing to root.

did you change the uuid?

Mark_667 · 01-17-2012, 09:18 AM

Yes, I changed the last character in the UUID from a d to an e, don't know what impact that'll have but it got me past the immediate problem. The .gvfsdirectory has dr-x----- permissions with me as the owner but I can't modify the permissions and when I try to rename it it says that the device or resource is busy. I'm currently booted into Xen so maybe that's using it, although there's nothing in the directory itself?

Just rebooted into the default kernel using KVM and got exactly the same issue, does anyone have any advice?

work around
you can create link from home dir
#mkdir vm
ln -s vm /var/lib/libvirt/image/vm
and then go virt-manager, and added as new storage pool that should work

Mark_667 · 01-19-2012, 04:15 AM

I did the following:

Code:

virsh pool-dumpxml default > pool.xml
edited pool.xml # with new name and path
fusermount -u ~/.gvfs
virsh pool-create pool.xml
virsh pool-refresh name

I successfully deleted the directory and created a new pool but for some reason I don't see any difference in Virtual Machine Manager. What else do I have to do to be able to see the pool?

I'm still getting

'Libvirt connection does not support storage management'

after uninstalling and reinstalling QEMU and KVM and still get

Quote:

when trying to create a new pool through the wizard. This is really holding me up and any help would be really appreciated.
