    Proxmox VE 7.3 released!

    Yes, it was the timestamp on /etc/pve/authkey.pub that was the cause of the problem. But I appreciate your answer and help. Have a nice day!

    Proxmox VE 7.3 released!

    Hi Time-sync is set up and working, but he timestamp of /etc/pve/authkey* was too old! The test-cluster is not running 24/7, so maybe something went wrong, when I updated it after just firing it up having been shut down for some days. Anyway this fixed the problem, thanks a lot for your advice...

    Proxmox VE 7.3 released!

    Hi I've tried it in Firefox and also tried using "Incognito-mode" on Chrome. Same result, I'm kicked out after a few minutes. And I have absolutely NO 3rd-party software on this system. I've installed some Debian packages like deborphan, members, and ethtool, but I can't imagine them interfering...

    Proxmox VE 7.3 released!

    Does anyone experience to be logged out of the web-interface of this new version after a few minutes with this message "permission denied - invalid PVE ticke (401)". Because I do, and I can't seem to find a setting for timeout like this. Is this a bug?

    Network packet loss in high traffic VMs

    Hi, I don't think you can do that, and that also makes sense, I think. In the end it is the physical interfaces, that handle the input/output, so it makes sense that it is those interfaces, where you can modify the buffer-sizes etc. All the logical/virtual interfaces will then benefit from...

    Network packet loss in high traffic VMs

    Hi mm553 Yes, I increased the buffer-sizes. After experimenting with the tx-size I settled for 4096 on both rx and tx. And it has definitively helped. If I run my tests, there a can still be a few retransmisssions left, but in the order of 0-50 on my standard iperf3-test. Before it could be in...

    Network packet loss in high traffic VMs

    Ok, but that must have been introduced on my systems by upgrading from ifupdown to ifupdown2. Thanks for the info!

    Network packet loss in high traffic VMs

    Ok, I finally solved it. It turns out, that I should have had the package ifupdown2 installed, which I didn't have. When this is installed - the pre-up stuff works as expected. I find this a little strange since these proxmox-hosts are all fully updated to the very latest version. Shouldn't this...

    Network packet loss in high traffic VMs

    Hi vesalius Thanks for your feedback! >> Did you try: pre-up ethtool -G <interface> tx 4096 rx 4096? No, actually I didn't. But now I will. I've been having a hard time finding some documentation on this. And i'll be back with some results and considerations.

    Network packet loss in high traffic VMs

    Hi Mika I'm investigating the exact same symptoms on a system at work. And the buffer-size should be changed on the underlying physical nics, I guess I've found out that it's quite easy to increase the ring-buffersize using 'ethtool -G <interface> rx <size> tx <sixe>', but my problem is how to...

    Issue with upgrade from 7.0 to 7.1

    Hi Tom Seriously..., 'apt-get upgrade' should be considered safer than 'apt upgrade'? I get that upgrading in general can go wrong, but could you elaborate a bit on this? Danish greetings Hans Otto

    Wondering about declining backup-speeds...

    I feel that the speed of backup has declined lately, so I'm wondering, whar other people experience. My VM's run of a Synology NAS using NFS3 with a 10 gigabit/s link. The NAS itself has it's disks in a RAID6 configuration. If I test the disk-speed from within one of the Linux-VM's using 'dd' I...

    Backup performance

    After the latest upgrades, that I guess for some part has to do with the Meltdown/Spectre-problem, I experience a huge loss in performance when I do backup of VM's. And I mean HUGE - more than 50%. Has anyone else noticed something like this?
