Hardware Info⌗
All of this was taken via an Debian 12 system (Bookworm / kernel 6.1), so your kernel may be configured slightly differently

CPU is very modern with virtualization support. 1 P-core (2 threads) + 4 E-cores (4 threads) gives us the weird number of 5 cores and 6 threads. Linux is of course very good at scheduling across P/E cores.

The two NICs are an Intel i226 (2.5G) and Aquantia AQC113 (10G NBase-T). Neither are limited in PCIe bandwidth. SATA is via an ASMedia controller off PCIe. The extra NVMe drive I added (Samsung) is in a different IOMMU group, in fact both of the NICs and both of the SSDs are in their own IOMMU group if you want to pass any of them through to VMs.
