When I create a dir type storage pool, it spits out the following error.

Error creating pool: Could not build storage pool: failed to create directory ‘/media/matrix/sdb9/pool’: File exists

The target path of the pool is /media/matrix/sdb9/pool/. No matter what directory I choose as the target path, it always shows this error.

Any idea?

Hi, In Stage 1, Step 3 you say that “One important thing also is to give the right permissions and ownership for this directory.” What exactly are the permissions I need to apply to the directory? When I choose the directory for the pool, VMM changes the ownership to root.

I’m trying to create the storage pool on an additional drive with partition type Linux LVM, formatted as EXT4 filesystem. I get to the step where I use VMM to create a new pool in a directory in that drive. I then created a volume in qcow2 format in that pool. When I try to create my virtual machine, and select this image, I get an error that reads: “The emulator may not have search permissions for the path ‘/media/it/BAY2/Spool1/NetSUS.img’.”

It asks if I want to correct this now? and I choose “Yes.” I then get the following error: “Errors were encountered changing permissions for the following directories: /media/it : [Errno 1] Operation not permitted: ‘/media/it'”

How do I fix this?

Meanwhile, I’ll try to create this VM in the default Pool.
