No virtualisation in Fedora 21 on Mustang

[Marcin Juszkiewicz]

In case you do not know yet: there is no virtualisation support
in Fedora 21 on APM Mustang. Looks like one of 3.18-rc commits
went into 3.17/stable tree and disabled it for us.

[root@pinkiepie virt]# LC_ALL=C virsh create hrw-f21.xml
error: Failed to create domain from hrw-f21.xml
error: unsupported configuration: Domain requires KVM, but it is not available. Check that
virtualisation is enabled in the host BIOS, and host configuration is setup to load the
kvm modules.

And I have been told that I need a 3.19 kernel for some future uboot 
features for Allwinner...  ;)

Fixed in kernel-3.17.4-302.fc21, which has been built on primary but not yet 
for aarch64. For testing a scratch build can be found here:

http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=2816858

If you do test, please add karma[1] to help move it along.


Regards,
Paul

This issue seems to have returned with F22:

# dmesg | grep -i kvm
[    0.298500] kvm [1]: GICV size 0x2000 not a multiple of page size 0x10000
[    0.298597] kvm [1]: error initializing Hyp mode: -6

# uname -a
Linux mustang.home 4.0.0-0.rc5.git4.1.fc22.aarch64 #1 SMP Thu Apr 2 09:22:12
UTC 2015 aarch64 aarch64 aarch64 GNU/Linux

There's a bug report here too: https://bugzilla.redhat.com/show_bug.cgi?id=1208768

Thanks,

Thx. Marked as duplicate of [1] which has DTB to solve that.
