Hi, Any further thoughts on this? Seems a bit of a mystery. The PCI dump looked fine. I would like to return this card back to Amazon in the next few days. So if anybody needs any more debug info please let me know. I'll contact you off-list. I do plan to retain the other NEC uPD720201

Re: My USB card is a bhyve killer

Hi, I have a PCIe USB card which is exported to the bhyve vm using passthrough. I have tried to use the card in Ubuntu, Debian 8 and Centos 7. Each time the OS has given a segmentation fault on bootup and killed the bhyve session. This is what i get in the bhyve-log: Is stderr logged anywhere

Re: Bhyve Broken: whose fault (AMD, FreeBSD, ZFS ...?)

Hi, What should be next steps here? This is repeatable. The host is stable (it can makeworld -j32 in about 25 minutes ... so it's hardware seems good). Is this an AMD bug? Is it bad to use ZFS ZVols? ZVols are fine. Is the guest panic a spinlock timeout ? I believe this is a bug in bhyv

Re: VNC stuff

Hi Rod, r302504 is not likely to be MFC'ed at this time, this is the e1000 driver and man page. This code has known issues at this time and is an action item list on the bhyve developers work list. The e1000 driver was MFC'd 11 months ago. The issues are currently only with Windows - it wor

Re: VNC stuff

Hi Rod, Do we want the VNC/Auth fix (once cleaned up for Coverty issues) in the 11.1 release? Doesnt this allow a lot more clients to connect to the fb? Or is it only a few clients that are being pendandic about using a questionable authentication means? The main one is the OSX built-in cli

Re: VNC stuff

Hi Zane, I assume that means the VNC/fbuf stuff as well? Not seeing that that currently in 11-STABLE. Sure you don't mean 10-STABLE ? The uefi graphics code was committed 11 months ago: https://svnweb.freebsd.org/base/stable/11/usr.sbin/bhyve/pci_fbuf.c?view=log later, Peter. __

Re: Windows Server 2016 as guest on bhyve 4k emulated drive

Hi Artur, I can not explain how Windows comes to 8192 bytes. As explained in Jeremya F's email, that's the zvol default record size. about 512E drives. According to

Hi Artur, if the option 'sectorsize=4096/4096' for the emulated drive specified, the installation process of "Windows Server 2016" completes the first stage ('Copying Windows files', 'Getting files ready for installation', 'Installing features' etc.) and fails after rebooting to the second stage

Re: dos in bhyve

Hi Andriy, I wonder if anyone was able to run any DOS variant in bhyve. I've run vm86 mode in Linux but that doesn't really count :) I tried FreeDOS using BHYVE_UEFI_CSM firmware, but it seems to just hang. Try looking at the CSM/BIOS debug output that is available on the bvmcons debug

Re: bhyve fbuf and keys on the numeric part of the keyboard

Hi Christian, After having used bhyve for servers for quite a while, I have just started using it with the graphical console using vnc a few days ago. This stuff is awesome. Having a native solution for virtualization on FreeBSD is great. However, I had some trouble with keyboard mappings and

Re: OpenBSD 6.1-snapshot no longer works in bhyve

Hi Jason, FYI, 6.1-release and 6.1-snapshots will not boot at this stage. I have my new production kit arriving so I can test on different hardware to determine if this is a CPU rev. issue but thought I'd put it here to get the thought processes working on it. I am running 11.0-release p8 Y

Re: Host filesystem in Bhyve

Hi Jakub, We've been using FreeNAS 10 (now Corral) as our testbed for virtio-9p for over a year now and I think at this point it's stable enough to be upstreamed. :-) Please expect phabricator diffs in the upcoming weeks! Great to hear ;) So... any news on a FreeBSD 9p client ? later, Pet

Re: Host filesystem in Bhyve

Hi Rajil, It seems that FreeNAS 10 is able to expose the host filesystem to bhyve sessions. Is there any plan to bring that feature into FreeBSD? I'd like to see it happen but it's really up to the iX guys who wrote that code to get it in. later, Peter. __

Re: bhyve passthrough problem after updated host to 10.3

Hi Sergey, Now, after experiments I can say the card can work only on 2 slot and function=function on host. Example: -s 2:1,passthrough,3/0/1 It's even worse I thought. The network card work only if spare slot with a disk device (may be any device, I did not try). So, it works: -s 2:1,passthr

Re: Windows XP

Hi Frank, bhyve doesn't support anything older than Vista, That's correct, though I'm hoping to support XP and Server 2003 at some point. and I'm unclear as to whether it supports 32-bit versions of that. It doesn't, nor any 32-bit version of Windows after that, mainly since they requ
