Hello, we tried to migrate some Windows 2008 and 2012 VMs from Xen to KVM, but installing the VirtIO viostor.sys driver fails, because the signature of the driver doesn't seem to match what's stored in the corresponding .cat file.
On the other hand installing the drivers during a fresh install from the beginning never had any problems. We use <https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/virtio-win-0.1.104-1/virtio-win-0.1.104.iso> but also tried "virtio-win-0.1.103.iso" and "virtio-win-0.1-81.iso". Running the following command on 0.1.104 prints (among others) the following sha1hash: > "C:\Program Files (x86)\Windows Kits\8.1\bin\x86\signtool.exe" /verify /v /kp E:\NetKVM\2k12\amd64\netkvm.sys ... > Hash of file (sha1): 135E3AA23217610AEE8046F68550B0BA86F4EAE6 > "C:\Program Files (x86)\Windows Kits\8.1\bin\x86\signtool.exe" /verify /v /kp E:\viostor\2k12\amd64\viostor.sys ... > Hash of file (sha1): EF11F5E539EEE0A9DB6DF3710A0DAA35066C5607 Looking into the corresponding .cat "Security Catalog File" - netkvm.cat contains the above given hash for netkvm.sys, - viostor.cat contains 55FC4DA2EE96ECC3FD4865680436DCDA6B8C6BDD instead! Running "sha1sum" on Linux print some completely different hashes, so I don't know what the Microsoft tool actually hash: > # sha1sum /cdrom/NetKVM/2k12/amd64/netkvm.sys > /cdrom/viostor/2k12/amd64/viostor.sys > 1aa91c8e1d7680457d92c1875810a79f68af536d /cdrom/NetKVM/2k12/amd64/netkvm.sys > f39bc2b561091addfcac30e370227c91700d2698 > /cdrom/viostor/2k12/amd64/viostor.sys Is this a known issue? Are there some (working) alternatives? Are there some Linux tools to work with the .cat files and signatures to make sure they match? Is there some better mailing list for VirtIO Windows driver issues? Some more background for our migration procedure: - The VM was installed some years are on Xen. - The GPLPV drivers were added afterwards. - For the migration the GPLPV drivers were disabled and then removed. - A 2nd VirtIO hard-disk was added in KVM to trigger Windows to request the virstor driver. If you need any more data, just ask. Thanks in advance Philipp Hahn PS: data was copied by hand from Windows, so it might contains copy-paste-errors. -- Philipp Hahn Open Source Software Engineer Univention GmbH be open.
