As EX-44 come with Intel Core i5-13500 which have 6 P-core and 8 E-core the price/performance is very lucrative to opt-in even with ECC addon added.

Do anyone uses proxmox on this CPU???, can proxmox handle both P & E cores also what about iGPU, does it work properly with passthrough?

Has anybody here run *BSD as a virtualization host?

Not_Oles — Sun, 15 Jan 2023 04:21:45 +0000

FreeBSD has bhyve as a virtualization host. I was just reading "23.6.3. Creating a Linux® Guest" at https://docs.freebsd.org/en/books/handbook/virtualization/ and I wonder, has anybody here tried a *BSD virtualization host? Thanks!

GNU/Linux (Debian) Virtualization on macOS

Amitz — Wed, 15 Jan 2020 18:43:19 +0000

Cheers my dears,

I try to virtualize a Debian installation under macOS and use VirtualBox for this. But I hate VirtualBox. Are you aware of any better solution? Thank you in advance for any good hint!

Kind regards

Struggling a bit with a Debian Linux bridge configuration

CamoYoshi — Thu, 30 Jan 2020 05:28:43 +0000

Hello folks,

First time post here but been lurking for quite a while since 2015 on "the old world". This particular issue has stumped me and I'd like to try and pick someone's brains for some help.

Here's my setup: I have two IPs being used; one for the Debian Linux system in question on the bare metal hardware, and a second IP used by a Windows Server VM running in KVM with libvirtd.

I recently switched over from one dedi to another. On my old dedi, I have a network config that looks like this:

auto br0
iface br0 inet static
address 203.111.0.114
netmask 255.255.255.248
gateway 203.111.0.113
bridge_ports eth0
bridge_stp off
bridge_maxwait 5
dns-nameservers 1.1.1.1 9.9.9.9 74.82.42.42
dns-search example.com

I then set another IP, 203.111.0.115 manually in the VM itself. This works great on this old dedi!

However a newer dedi I am moving to, with the same version of Debian Linux installed, has a slightly different setup. With the old dedi, I get a /29, but this new one, I only get 2 IPs out of a shared /24. So, my network config now looks like this on the new dedi:

auto br0
iface br0 inet static
address 203.111.0.214
netmask 255.255.255.0
gateway 203.111.0.1
bridge_ports eth0
bridge_stp off
bridge_maxwait 5
dns-nameservers 1.1.1.1 9.9.9.9 74.82.42.42
dns-search example.com

I then set a static IP on the VM just like before. Both systems can ping the default gateway at 203.111.0.1, but cannot reach anything beyond it. The Linux system's route table shows 203.111.0.1 as a default route, but is unable to pass any traffic beyond it.

I've made sure that I've gotten things like the bridge utils package installed on both systems.

Now here's the real wrinkle:

If I take out the bridge component on the new dedi, and just set the interface up without the bridge, like so:

auto eth0
allow-hotplug eth0
iface eth0 inet static
address 203.111.0.214
netmask 255.255.255.0
gateway 203.111.0.1
bridge_ports eth0
bridge_stp off
bridge_maxwait 5
dns-nameservers 1.1.1.1 9.9.9.9 74.82.42.42
dns-search example.com

This works perfectly fine and I can get out to internet destinations, as intended.

I've opened a ticket with the provider and they pointed to a issue in my network config, so I'm kind of stumped. I don't know what I'm missing here so I'm hoping someone could point me in the right direction. Thank you all in advance!
