[OmniOS-discuss] anything change since 151005 that would cause KVM to stop working?

[Kent Watsen]

I posted to the list about 6 months ago my attempt to compile the KVM 
driver for AMD.  I was ultimately successful (thanks Theo and Eric!)

Now, after some delay, I've decided to it again with a fresh install of 
OmniOS (151006p).  I followed the same steps to build illumos and the 
kvm driver and install it.  But it doesn't work anymore - this is on the 
*same* box as before...


# add_drv kvm
devfsadm: driver failed to attach: kvm
Warning: Driver (kvm) successfully added to system but failed to attach


Looking at `dmesg`, it looks like there is namespace collision?
