If you place all layer 3 addresses on the bridge interfaces and not on any member.

I end have no console. I ended up in a state where it turned out booting went to stand-alone mode for a manual fsck. So: no ssh access or any other access. I ended up using the Windows Dev Kit 2023 with the boot device in order figure out what was going on and to the the needed fsck. Turns out that if I'm building, installing, and booting my own kernel, there is a way around that replacement of efifb by using: nodevice virtio_gpu in the kernel configuration, so that the boot ends up using efifb (no replacement). If course, this does not help with kernels from official FreeBSD builds. Is there a way to disable virtio_gpu for something that runs an official kernel build (where virtio_gpu is built into the kernel)? =3D=3D=3D Mark Millard marklmi at yahoo.com From nobody Fri Feb 14 00:50:03 2025 X-Original-To: freebsd-virtualization@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4YvD3y5s4Gz5nX22 for ; Fri, 14 Feb 2025 00:50:22 +0000 (UTC) (envelope-from marklmi@yahoo.com) Received: from sonic308-8.consmr.mail.gq1.yahoo.com (sonic308-8.consmr.mail.gq1.yahoo.com [98.137.68.32]) (using TLSv1.3 with cipher TLS_AES_128_GCM_SHA256 (128/128 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256) (Client did not present a certificate) by mx1.freebsd.org (Postfix) with ESMTPS id 4YvD3x3DDHz3jPc for ; Fri, 14 Feb 2025 00:50:21 +0000 (UTC) (envelope-from marklmi@yahoo.com) Authentication-Results: mx1.freebsd.org; none DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=yahoo.com; s=s2048; t=1739494219; bh=vaevIU41A5vpkCDBJftQsD9u0fuzxGBBzHPWXVoxwcg=; h=Subject:From:In-Reply-To:Date:Cc:References:To:From:Subject:Reply-To; b=HNOuEylWGB7+symOwPwMaDhjxCsrJG8B8WNJ9OmWlFnQlSIGMEn7MBVMrMmLuOVllJSrMftHYwQJ80jbmbk/n5gzsxCuwvBnVO1+BpTEFG77WWIyXV5dd6ZwIcRxi+ihxonu6N3ZTfpR/dgv+pO3R8mpnBTnV8ZDL3bxQoe/nkNQTf22gZ+4Xmf3aXfTU5+oFucP4zhCQivHq/op2mS7q5casjHdpzkl/ve4/2zGAEVkm3g6+qPr2J9gF5dhi8q19cOwOsG1Dg69TxZCXjLVjDLHPGOS2fYnLSB8Bo4jsm5ID//lKvZlyrrti+ZO9mGvdmFQuUS+/1GagfxvE647gQ== X-SONIC-DKIM-SIGN: v=1; a=rsa-sha256; c=relaxed/relaxed; d=yahoo.com; s=s2048; t=1739494219; bh=7NCwzyRgpIpcfve2M6e74SkC587oJ5G4/EO9axfdvsG=; h=X-Sonic-MF:Subject:From:Date:To:From:Subject; b=q+xmncyEMNO0y8Kpb/dmQ7Z3Ay6JDhWtHnbu3oVi+phgjfCKnn/axwlpg6us+BWktkTl9ctlo+rdnZ/YYUnlMAbz7LiHetOYDwrm28dzuLIazkRDSbwoUbueYFHyIbYgALcG4WQwffpb2ilgsfBLHStRUV+oL4xtvLj6EQZp7flrH+vhspVApF/8+T1JY7J9G0xKVIZsugIRuEG1Xz+a/ialoCGEz248k+vK38sZSe3hziBH3qF3VQwYsF9TR0XjsKrnX0Sk2owbeTSndm5DgeiO8VBUJABoy9SB33SLpO1V0n2t1noOCC2C5ejD4tukoYPp0lYq/q2gu18UxRnizg== X-YMail-OSG: 38bukO4VM1k9wZdkD8w_Ko7vvukFxY.IV9FFrLiTAn.CyO4CsNG2UFds6omMuK9 a.wRMdwmXahwZORAGIwDq_ij2WF7TIH3kIh0Q_aKyuPTCZTXTenaqnka_DhQKUzRL3b5rmAjvzfY FeHEdgfsXMF6Pf7iNph_da4qEQ6BXvISs117VPL465vrLrdTCwlnHL0NES4ja1cZSRqNONwbtEtr sBEzfoblFYXFFkHsheJRyEBalKyiVQiqjiEHH6p4pr0DGQo6uqT8Rhn.w31URImqpfacnbuWw77H 6kMWvZ7Vs6XzoVHeIqILei98Cl_99g_GsLyyyyGlqgUXbqaibr3V9O7uz0K98LVE3YNz2U8X8.KF U5n46zSBw5mNdlo39VpsylrDpLT7X.kWIUu6vI6TsDif9TvydERToGcTp640fYbAcKFmEJJ2Zgqe Y9aqaVW0ykDe7mgdTziR.r3MXMPVud7qMqr9eAELkSs0BSWFWqhSytrBmYI8wJJhQweqL6vQeLtW iBXbTQHJKTpiIrgXR.P2fo0zrZSWKiwykEATkwGxdAaMuyXtu4Cl7gKMrZA6Hzd3jYSasJPfw3Ql VG_fm8bCY57vKuDkNRy1zyH5_RMimQAIcH._Ri0nR3kAPqZzJq5fmSFA6HrRNlZmFffTD.ntZ0TV KGzVm5r3c09sbO8ofJ8A20ooNGzHWeUbQ8eubkIHCWHif2B28XvI16vmuvWku91HOIJID0zUz8k4 mNusLEj5E3ppfX0G.dUl.gGHgMQX6vKFBDkv8DTdan6zp5v4YsPb.vtZ2PKwQjBUq.255h0QhDqh sRk.qoxx8qW_uxZuW5bkKMHZdzeH56Ncey6xmCp3Ovv.bY_B1lzmvcu0aXC0IsQnioiwYyZc8x8P ijfLgXkGRQ3B_kWmbdmrr3p3DWs3jkYpaWW4MHKdG71pttqET3oRBK8.xhHxw_VDFMXPHxsz1Byy BrVHNUJ6HH64_fT0dGbJnxAzsBq3.Rgjog56Nh7s0w57nYI1QcN83X8aAeVvkem5LrdMh2LCp2w_ rZnc9wpl_rYtewty8wZjCd0s1MwHHDo9oZezW2wM0UZqxY3XLSLLE4j6Bi.hF6LbWjFyPgh8KL2c zwccHGx25.qb9U7HpL9SsEBo4OSQT1q1VSSoqW8Up6HOUtnS9i6_pVvwa8IxgNjZH0aG.XqPHwg_ UoBwY8YuVVP.v57tWnBZ6A2aBOHqi45InwmxZTp2K8BV3KHuTdkhQJl.T5zDTGehNx0ioC0.K.1F C2w3cFbT7I7zpQwMPVjPCTuCwq9kwjCe_qY35vTs6ewDFilneh8.VnrOZvR8o1xoq3zsWBKkxp6x vYHJY3Lg.k13cKpEgecg9JyyNTrBZpoxJUYtFAjefi0xD0zjYj72s9zYqqr5E7hJ960jf4Skb30I 7v3KG.QqWT4_Vufry1vcJEYk6TSof3Mg31nmk2qb_EX2LNpCYsmEzb4AuOji_XfS1Zvhbgl9MDEZ Cw68Ba0w96htGthiajKfkf0G9XOx3FSUTuN7fHCs3xNFzL6d2kwbltKU.quv2LNR.d0EJdlkR4.N 6lWbCcM9VZTq5rOAzrS4W7Qw8UCxl0EIzkAG8Q6TBjtpRY7dJ5x3GoRnaAzrfMw6xk8Oa7YvAH9I 3LcymhzqIzVpjhsqxx9J66WeEewcZvD1sH_11dLqIOMTFLDci_np.nCt.E3XvxAtgzUmUp.NPZ3C _DU.L1D9amvGq2YvAFz.iaHpw.ZCb6zAgwzcqshxXZAqIfXIpFZrhXtT3hq4fv20L3hBtG_KqKp.

How would that lead to not doing: VT: Replacing driver "efifb" with new "virtio_gpu". ? Using the menu, all 4 combinations stopped in the same place and way until I built and used a kernel that did not have virtio_gpu at all, if I remember right. Both efifb and virtio_gpu seem to be for the video side of the alternatives. (It seems that something more is needed for virtio_gpu to end up providing a console, if it can. May be the Parallels Toolbox for an actual Linux provides what is missing for that kind of context? I'm not after X11 or such, just having an operational console for seeing information and dealing with problems when ssh can not be used.) I've no clue if the issue is specific to just Parallels or not: I've really only used Hyper-V (only getting it working for FreeBSD as a guest OS on amd64) and Parallels (aarch64 currently). So I do not know if it would be worth a tunable to, say, set the vd_priority offset from VD_PRIORITY_GENERIC, such that it could end up not replacing efifb.

It may be something that works for a "real" Other Linux. When I tried the non-Linux plain Other, FreeBSD panicked while trying to support the virtio code. As stands, I'm booting my own kernel that omits virtio_gpu (so that it does not replace efifb). efifb seems to work just fine for my limited range of use. Parallels allows me to operate my normal boot media as the as the storage for a VM. It is the same media that I use on the Windows Dev Kit 2023 and that I sometimes use on a RPi5 as well. Software for Apple Store distribution was not allowed to do such last I knew: It involved privilege escalation. See: https://github.com/utmapp/UTM/issues/5346 That is one of the reasons that I'm using Parallels.

May you try with device.hints(5) ? It can mark a device disabled ( no driver loaded ) when probing, so you = can avoid `VT: Replacing driver "efifb" with new "virtio_gpu"` and should have the = same effect with `nodevice virtio_gpu`.

Hi,
I am trying to configure bhyve vm with support of virtio-console, the following option is added to bhyve command line

-s 3,virtio-console,port1=/test/console.sock

However when trying to connect to socket with socat trere are no input/ouptut is observed.

Has virtio-console ever worked ?

Please advise.

I tried with the following command, and got the same result.

/usr/sbin/bhyve -H -P -A -c 1 -m 1500M \
-s 0,hostbridge \
-s 6,virtio-console,0=/tmp/vtcon.0 \
-s 31,lpc \
-l bootrom,/tmp/BHYVE_UEFI.fd \
-s 1,virtio-blk,/tmp/fbsd.img \
-s 2,virtio-net,tap0 \
tmp


I also able to connect but the bidirectional connection is not happening

socat - UNIX-CONNECT:/tmp/vtcon.0
ls

PS: if I use null modem emulation instead virtio-console, then connecting with cu is not an issue.

any ideas ?

Thanks

Hi,

Has virtio-console ever worked ?


Yes it works, I just tried it using sysutils/vm-bhyve (just add
virt_console0="Yes" to the configuration file).

Based on the logs, these device settings are used by it:

    bhyve devices:
      -s 0,hostbridge \
      -s 31,lpc \
      -s 4:0,virtio-blk,/dev/zvol/zroot/vms/freebsd14-test/disk0 \
      -s 5:0,virtio-net,tap0,mac=58:9c:fc:aa:aa:aa \
      -s 6:0,virtio-console,0=/vms/freebsd14-test/vtcon.0

I could connect to /vms/freebsd14-test/vtcon.0 using socat:

    socat - UNIX-CONNECT:/vms/freebsd14-test/vtcon.0

Inside the vm it's /dev/vtcon/0.

I am trying to create a vm using freebsd cloud image and connect to guest OS terminal with virtio-console and socat(no X11). When spawning the vm the unix socket indeed is created, however when I connect to it with socat nothing is being shown(not actions on any terminal commands as well). Also, I noticed there is a kernel module(virtio_console.ko) and apparently I believe it has to be loaded it, not sure here.

I am trying to create a vm using freebsd cloud image and connect to guest OS terminal with virtio-console and socat(no X11). When spawning the vm the unix socket indeed is created, however when I connect to it with socat nothing is being shown(not actions on any terminal commands as well). Also, I noticed there is a kernel module(virtio_console.ko) and apparently I believe it has to be loaded it, not sure here.

But the console display stops updating after: 'VT: Replacing driver "efifb" with new "virtio_gpu".' is reported.
