Re: bhyve uses all available memory during IO-intensive operations

There was a standards group but now the interfaces used buy the Linux virtio drivers define the de facto standard. As virtual interfaces go they're fairly decent. So all we need is a backend. The one thing FreeBSD doesn't have that I miss is CPU hot plug when running as a guest - or at least a

Re: bhyve uses all available memory during IO-intensive operations

ector size? I would err somewhat larger, the benefits of shallower indirect block chains will outweigh the cost of RMW I would guess. And I think it should be your guest file system block size. I don't know what ext4 is, but ext2/3 was 16k by default IIRC. -M > > - .Dustin >

Re: bhyve uses all available memory during IO-intensive operations

One thing to watch out for with chyves if your virtual disk is more than 20G is the fact that it uses 512 byte blocks for the zvols it creates. I ended up using up 1.4TB only half filling up a 250G zvol. Chyves is quick and easy, but it's not exactly production ready. -M On Thu, Nov 30, 2017

Re: Issues with GTX960 on CentOS7 using bhyve PCI passthru (FreeBSD 11-RC2)

I hope you keep it up or at least figure out what the driver is doing. If they haven't explicitly put in the license terms that virtualization is forbidden for consumer cards, there's nothing wrong with hot patching the driver ... assuming that they don't do things like Skype does where it

Re: Issues with GTX960 on CentOS7 using bhyve PCI passthru (FreeBSD 11-RC2)

Is the VM checking documented in the driver notes somewhere? I have a Titan X that I need to run CUDA on and would be much happier if I didn't have to actually switch back and forth between FreeBSD and Ubuntu on my desktop. Are we new fairly certain that this won't work? (Yet another reason to go

'production grade'. And virtualbox does not come close to kvm/xen in terms of performance/management features . Also the whole Oracle thing ... I was curious about KVM support because of coming across the old port (2007). What happened to it ? 2011/6/30 K. Macy kmacy at freebsd.org: On Thu
