dp you mean switching from vmbrX 1500 --> vmbrY 1450 with the vm online ? if yes, I think currently it's only unplug/replug the tap interface on the host side, but I'm not sure it's changing the value inside the guest. (The only way is to unplug/hotplug the nic I think, as the mtu in the...

10 year ago, ovs had features that linux bridge didn't have (vlan-aware for example). But today, maybe the only interesting feature they have is port-mirroring. The whole sdn stack don't use ovs at all (including for vxlan,evpn,...). I don't like ovs personnaly, because you have an userland...

use the vmbrX directly . (Not sure why it's vlan4095 on vmware ? is it hardcorded 4095 trick in vmware to allow all vlans?) no Both are the same, choose what you prefer. (sdn allow more complex setup like vxlan,evpn,... but for simple vlan, this is the same)

"bridge-vids" are the list of allowed vlans in the bridge. (by default it's 2-4096 to allow all vlans). If you add a vm interface with a specific tag vlan, it'll not work if the vlan is not also defined in bridge-vids.

By default, if host don't use 80% memory, the balloon driver is using 0 memory. (so the vm is using the max memory). and when the host is > 80% memory, pvestatd deamon try to increase the balloon a little bit on each vm to decrease host memory to 80% again, with min_size as maximum target for...

when your host is reaching 80% memory, the balloon driver of each vm where it's running is increasing . The memory take by the balloon drivers, is gived back to the hypervisor. Only linux, you don't see it, it's like the memory of the vm is decreasing, because the balloon driver is well...

The results seem quite low indeed. Qemu itself is able to reach 200~300k iops with 1 core. (I'm working to add support for mutiple iothread to increase the performance up to 600kiops by disk, but you are far from reaching the current cpu limit). (I'm not sure about the performanc when doing...

Hi,thanks for the report. I have send patch to the mailing recently to improve the performance of secure erase, it's not yet commited. But I didn't notice this bug with volume activation. I'll look at it next week. (and I'll forward it the dev mailing)

yes sure. (everything you can do in the gui is using api)

never tried it but : https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/7/html/virtualization_deployment_and_administration_guide/chap-kvm_guest_timing_management To enable the PHC device, do the following on the guest OS: Set the ptp_kvm module to load after reboot. # echo...

you can't with lvm-thin, because the metadata volume can't be shared. You need to use classic LVM (and snapshot have been added in pve9 for them)

It's quite possible that your are cpu limited, as currently vm can only use 1 core for 1 virtual disk. Multiple threading (with multiple iothread by disk), should be available soon, I have already send patch to the proxmox dev mailing list.

simply use a different subnet like for example 192.168.0.0/24 with 192.168.0.1 && 192.168.0.2 for your server 25g && backup 10gb card.

more than one OSE per nvme will not help. non PLP are really like 500iops 4k write vs 20000iops for plp drive. At minimum, use cache=writeback, it should help to avoid small write when possible (merging small adjacent writes to big write)

Hi, For people sleeping at the hotel of the conference the day before, anybody interested to drink a beer ?

no, it's local on the node.

at minimum, if you use your arista as exit-node, (advertising the default route from arista) you should remove "exitnodes proxmox1-4,proxmox1-3,proxmox1-1" and peer with your arista router "peers proxmox1ip, proxmox2ip, proxmox3ip, aristaip" snat should be done on your arista too
