    Inofficial proxmox-backup-client RPM builds for RHEL-based distros

    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 ?

    How do SDN IPAM plugins assign addresses to VMs?

    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)

    How do SDN IPAM plugins assign addresses to VMs?

    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...

    Reserving HW resources for Hypervisor (physical machine) itself

    Reserving HW resources for Hypervisor (physical machine) itself

    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...

    Purpose of the internal interfaces

    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...

    KVM: VMXNET3 vs. VirtIO

    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...

    VirtIO-IOMMU

    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) ?

    VirtIO-IOMMU

    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.

    SDN Mutlicast for vxlans

    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.)

    SDN Mutlicast for vxlans

    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...

    SDN Mutlicast for vxlans

    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...

    Reserving HW resources for Hypervisor (physical machine) itself

    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...

    Reserving HW resources for Hypervisor (physical machine) itself

    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...

    Reserving HW resources for Hypervisor (physical machine) itself

    Thank you for the idea how to manually do it so, but my question was: is it possible from GUI/config file?

    Reserving HW resources for Hypervisor (physical machine) itself

    For example, OpenStack on every Compute node (one with Hypervisor) had a config file related to Hypervisor/Host specific configuration/tunning. Specificaly this file is named: /etc/nova/nova.conf And it has (among the other things) three sections like this one (with which you can reserve...

    Reserving HW resources for Hypervisor (physical machine) itself

    Hello. I have a question related to the Proxmox VE nodes (hardware/bare metal). Are there any possibility to reserve some hardware resources for Hypervisor itself, like: Reserved amount of RAM Reserved CPU cores Reserved disk spaces (if needed) Similar as it is possible on OpenStack...

    MACVTAP as future replacement of classic NIC+BRIDGE+TAP interfaces

    Advantage may be removing one layer (bridge interface) and therefore speed things up and having "lighter" configuration :) ... as i understand from IBM presentation there is speed up on net communication between VMs on the same node: They (IBM) comment the improvement using MACVTAP: HERE (There...

    MACVTAP as future replacement of classic NIC+BRIDGE+TAP interfaces

    MACVTAP support 3 modes, and one of them are plain bridge. ... as explained HERE (i am proposing this as an idea :) )
