[fedora-virt] Loading the KVM module (Fedora 19 on ppc64, POWER7)

[Andrej Podzimek]

Hello,

I'm trying to run libvirtd and KVM on a POWER7 machine. For some reason, virt-manager on a client says there is no KVM support. :-( The KVM module installed on the system cannot be loaded:

	# modprobe kvm
	modprobe: ERROR: could not insert 'kvm': Input/output error

There are no new messages in dmesg. Presumably, the file /lib/modules/3.10.11-200.fc19.ppc64p7/kernel/arch/powerpc/kvm/kvm.ko is readable; at least sha1sum can read it. This is how the error appears in strace (from open()ing the module to an unsuccessful kcmp()):

	open("/lib/modules/3.10.11-200.fc19.ppc64p7/kernel/arch/powerpc/kvm/kvm.ko", O_RDONLY|O_CLOEXEC) = 3
	read(3, "\177ELF\2\2", 6)               = 6
	lseek(3, 0, SEEK_SET)                   = 0
	fstat(3, {st_mode=S_IFREG|0744, st_size=273976, ...}) = 0
	mmap(NULL, 273976, PROT_READ, MAP_PRIVATE, 3, 0) = 0x1fffffad0000
	kcmp(0x3, 0x1ffffff68330, 0, 0x3, 0)    = -1 EIO (Input/output error)

The OS is a fresh Fedora 19 installation with kernel.ppc64p7 3.10.11-200.fc19.

Perhaps this could be a known issue or a glitch related to SELinux, but I have no idea what to try next. Could someone give me a hint, please?

Cheers!
Andrej
