Just wondering if it is possible to install windows on the 4.4.9? (I am running 4.4.9 and node 4.4.8, I don’t node is built yet for .9)

The issue I am having is changing CDs, when I try to change it get the following error: (Both ISOs are uploaded though the GUI on block storage, iSCSI)

This is https://bugzilla.redhat.com/1990268 It is fixed in: $ git describe 6094e672781f593767dc313ebd53d23334511f5a v4.40.90.1-7-g6094e6727 You need to upgrade vdsm. The only workaround for now is to use a file based storage domain (e.g. NFS) for the ISO images. When the issue is fixed, you can copy the ISO disks to another storage domain, and remove the file based domain. Nir
