I'm testing #virtio #native #context #gpu with #qemu today. Works with the #sdl backend but not #gtk for some reason. No joy with cross compiling the #iris driver yet but I still need to test with #amd graphics on my #ava box before I pull the patches.

#Proxmox #NUT #HomeLab #HowTo Step 6 : Update #Debian / Take #Snapshot / Upgrade #VirtIO / Manage Snapshots

Another addition to the Proxmox Series. You can watch the video, read the article and practice on the VMWare images that accompany the series.

My router is also my main disc dumper! #DiscPreservation #OpticalMedia #Virtualization #VirtIO #Proxmox

Is it theoretically possible to boot #Windows with a #9P root without having to create a disk image, similar to how it works on Linux? The only thing I found is #ninefs, which is very old and unmaintained and it's unclear if that's just an SMB replacement.
Motivation is explained here: https://wiki.qemu.org/Documentation/9p_root_fs
ninefs: https://code.google.com/archive/p/ninefs/
I'm not super familiar with Windows internals, so I'm not sure if this is possible with a driver or if it requires a custom kernel.

The #virtio #vulkan #qemu #pr is away. I've done a bunch of local testing on #aarch64 and #x86 guests but if you have the latest #virglrenderer and #mesa libs you can test the branch here: https://gitlab.com/stsquad/qemu/-/commits/pull-virtio-gpu-vulkan-291024-1 some platforms may need additional kernel patches.

Step 6 of the Proxmox-NUT #Homelab #HOWTO covers Debian and #Proxmox manual updates / Snapshots / #Storage and Snapshots / #Snapshots vs Backups / Upgrading #VirtIO.

1/2

I observed that #Suricata running on a #virtio interface in a #Proxmox VM does not see the traffic entirely, at least in our setup.

E.g., when running wget on the same VM to download a file from a different host via http, suricata sees only the request, not the response (in both modes af-packet and pcap).

In its logs, it complaints about an ioctl that it is not able to operate, and it suggests to use "ethtool -K rx off".

Another weird idea, i'd like to try:

adding a 3rd member to my #zfs mirror, but it's #iSCSI over fast ethernet over #powerline - put it in the cellar, 3 storeys down, see what happens.

I've got everything i'd need for a test setup - that little Wyse 3040 thin client has 1 USB3 port…
*record scratch, rewind*

I think #virtio NICs can be manually throttled to a fraction of "fast ethernet".

Hmm, virtualised, the test would exclude the weird old powerline bridges, though.

Back to Plan A, then!

Does anyone know if it's possible to make qemu or virtio present a drive as writable but discard all writes, or write to RAM and then discard?

re: https://aus.social/@voltagex/113104335330175774 I'd like to make this backup software think a drive is writeable as it doesn't want to do anything with read-only drives, while protecting the source image. Windows itself is also a problem with read-only drives.

Драйвер Ethernet для xv6

Xv6 - учебная ОС - рассказывает об идеях, что лежат в основе операционных систем. Научим xv6 работать в сети, познакомимся со стандартом виртуальных устройств VirtIO, деревом устройств DeviceTree, технологией Ethernet, сетевыми протоколами, возведем сетевой мост между виртуальными машинами.

ugh, there is no #virtio for PWM and ADC in the current spec

Not holding my breath there, but in case #sysprof performance profiling data can provide new insights to allow optimizing #GNOMEBoxes / #QEMU / Spice guest tools / #virtio graphics to provide faster Windows #virtualization on #Linux without VirtualBox, here is a fresh bug report on window dragging performance specifically: https://gitlab.gnome.org/GNOME/gnome-boxes/-/issues/1083
