I don't run illumos on Hyper-V but was running some Linux boxes on Hyper-V when there were no paravirt drivers available other than Microsoft's binaries that only worked with specific RHEL5 releases. Thankfully things have changed by now, even FreeBSD 10 does now work quite OK on Hyper-V. But illumos doesn't have any paravirt drivers for Hyper-V. Without boring you to much with Linux specificas what I can share based on the experience of running Ubuntu 8.04 on Hyper-V 2008 R2: - w/o a base VMBus kernel module Linux couldn't get more than 1 vCPU (documented limitation by MS) - w/o paravirt storage drivers, a guest is limited to 4 emulated IDE drives, no SCSI controller - w/o the paravirt storage you are stuck on an emulated flavour of the IDE controller which *is* slow in my experience. - Ethernet was only possible with the 100MBit emulated DEC, which is also slow. I guess the DEC NIC is still the emulated fallback in 2012 R2. In other words: A lot of guest OS would actually run inside Hyper-V, but in general Hyper-V heavily relies on having paravirtualized drivers in the guest, and without them it really doesn't make much fun / yield much performance. Now with FreeBSD 10 having some basic Hyper-V drivers (AFAIK vmbus,storage,network) under a BSD license "all you need" is someone porting those drivers over to illumos. ;-) That said: FreeBSD had both Citrix, NetApp and Microsoft working together in order to get those drivers stable enough for 10.0-RELEASE. The first 2 companies are known for selling products based on FreeBSD, so there was some commercial interest that backed the project. -- Mathieu ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
