bhyve passthrough fails
Hi, I am trying to pass an mPCIe device to a guest bhyve VM. I have the device set to use the ppt driver: # devctl set driver pci0:2:0:0 ppt pciconf -lv gives me the following output: ppt0@pci0:2:0:0: class=0x028000 card=0x197d103c chip=0x817910ec rev=0x01 hdr=0x00 vendor = 'Realtek Semiconductor Co., Ltd.' device = 'RTL8188EE Wireless Network Adapter' class = networ But when I start a FreeBSD guest with the vmrun script (sudo sh vmrun.sh -p 2/0/0 -c 2 -m 512M -t tap0 -d freebsd12.img freebsd1), I immediately get this error: bhyve: PCI device at 2/0/0 is not using the ppt(4) driver. I have virtualization set in the BIOS and am not certain what may be causing this issue. Any ideas?

Without such a feature, we can't replace all of our ESXi machines. -Alan ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
Re: bhyve passthrough fails
Hi Farhan, bhyve: PCI device at 2/0/0 is not using the ppt(4) driver. Just noticed this myself: looks like a regression :( I'll see if I can work it out and get a fix in. later, Peter. ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"

Re: bhyve passthrough fails
I would not mind sending you on-going feedback or debugging information if it helps. Could it be a chipset issue? This is a lower-end laptop. It can do virtualization, but the passthrough issue seemed to fail. I was on FreeBSD 11.1. -- Farhan Khan PGP Fingerprint: 782F 342B 5B08 0D2F F4E8 82C3 FFA1 CAE1 6536 51CA On Thu, Sep 7, 2017 at 10:52 AM, Peter Grehan wrote: > Hi Farhan, > >> bhyve: PCI device at 2/0/0 is not using the ppt(4) driver. >> > > Just noticed this myself: looks like a regression :( I'll see if I can > work it out and get a fix in. > > later, > > Peter. > ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"

It may be due to this (and also my issue which was on AMD, may be due to a reboot where I didn't enable the iommu). If that is the case, the error handling could certainly be improved :( You can check to see if there is an IOMMU available by looking for the APCI DMAR table: acpidump -t | grep DMAR later, Peter. ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"

Our vsphere environment still has life left in it but we never want to bet on one horse (I've been in too many positions where vendor lock has occurred and its been painful and expensive). However, where there are single hosts instances out at remote branches, it is bhyve all the way where we use to use individual instances of ESXi. So for your use case, it isn't there yet, but, if you don't need live migration, using zfs and/or iSCSI you could tool something together for offline migration of guests between hosts. Allowing you to get closer to the operating system (unlike the abstraction that is vsphere/ESXi), gives you the ability to take the excellent tools that FreeBSD has to offer and make them fit your application. ___ freebsd-virtualization@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
