It works also for Rocky Linux 9. Thank you for the job done. To Proxmox team: is it possible to include it in the official repo ?

Related to DHCP and Open Stack: DHCP on Open Stack More details may be seen on: 1. OpenStack --> DHCP (dnsmasq) 2. Networking-Nova 3. Details on design (dnsmasq+network namespaces inside Open Stack)

DHCP support will be great (inside VLAN for example). So, DHCP support is crucial in an environment where network segmentation is made on an easy way (VLAN). In my case, simple dnsmasq is great for that job. DNS service inside (VLAN) is also welcome. As i remember on Open Stack it is done in a...

Interesting post for further investigation on this topic https://null-src.com/posts/qemu-optimization/post.php

Hello. One and easy solution for isolating CPU cores from task/process scheduler is an option that you can use on kernel, and it must be defined in GRUB(2). This option is: isolcpus For example, if you want to reserve CPU cores 0 and 1, just add this opction at the end of the grub config file...

Hello. I just want to understand the standard OpenvSwitch/Linux native interfaces used in Proxmox VE, when using SDN/VNets: VNetINT is name of my VNet Looking at the OpenvSwitch level: ovs-vsctl list interface | egrep "^name|^status|^type" name : vmbr0 --> This is a Bridge...

Hello. I think that the latest Rocky Linux images can be found here: https://uk.lxd.images.canonical.com/images/rockylinux/

Maybe to late, but (answer from VMware): It looks that VMXNET3 is not emulated but using some kind of paravirtualization (at least when using on ESXi, not sure how it may work on KVM/QEMU environment --> it may be emulated or?). On the other side VirtIO s entirely paravirtualized (no...

So in the future it will be available as an (advanced) option [did not read the diff/changes in code]?. P.S. I assume that IOMMU part in GRUB2 kernel configuration will also be added (for Intel: intel_iommu=on and eventually: iommu=pt) ?

Hello. Since new kernel (5.14) supports VirtIO-IOMMU, maybe it would be a nice one to have it as an advanced option to use (as option: enable/disable). Linux kernel 5.14. and VirtIO-IOMMU More details can be found here: QEMU - VT-d (IOMMU) VirtIO-IOMMU explained Br, Hrvoje.

For now, i have no problems, but reading that it is in use in VMware and OpenStack, i was thinking that there must be a bigger reason for it (for example it is "lighter" on MAC learning etc.)

Multicast within VXLAN is a very good option; nicely described here: https://www.slideshare.net/enakai/how-vxlan-works-on-linux And here (on VMware side, but it is the same as in may be in Proxmox VE) is the good introductions of the issues with/without VXLAN multicast...

Hello. As i find out, some examples related to VXLAN and Multicast can be found here (didn't test it): https://git.proxmox.com/?p=pve-docs.git;a=blob_plain;f=vxlan-and-evpn.adoc;hb=HEAD As i understand the config, the difference is (inside VXLAN interface section): In Unicast: iface vxlan2...

Hello. When changing /etc/nova/nova.conf file on all Compute nodes: reserved_host_memory_mb=8192 # This is 8GB reserved_host_disk_mb=10000 # This is 100GB reserved_host_cpus=2 ... and restarting nova service. So when we look on the OpenStack, after above reservation is done on all...

Hello. So as it is possible on OpenStack and VMware (ESXi), primary for the system or even specific Host/Hypervisor/physical machines, on which you do not want to overprovision VMs/LXcs. In practice when you have a need to host the guest (VMs or LXC containers) that can not be overprovisioned...
