Re: [libvirt] [PATCH 1/5] virhostdev: Move IOMMU and VFIO funcs from qemu

The functions in question are
qemuHostdevHostSupportsPassthroughLegacy
and qemuHostdevHostSupportsPassthroughVFIO. At the same time the
functions are renamed to match 'vir' prefix instead of 'qemu' one.
I'm not sure I see the reason for moving these functions ? They're
QEMU specific surely ?
eg
@@ -1635,3 +1640,71 @@
virHostdevUpdateDomainActiveDevices(virHostdevManagerPtr mgr,
return 0;
}
+
+#if HAVE_LINUX_KVM_H
+bool
+virHostdevHostSupportsPassthroughLegacy(void)
+{
+ int kvmfd = -1;
+ bool ret = false;
+
+ if ((kvmfd = open("/dev/kvm", O_RDONLY)) < 0)
+ goto cleanup;
is going to be useless for anything except QEMU driver.

Daniel
