    [SOLVED] ksm-control-deamon

    I have now tried to force ksm to work by having two VMs that use more RAM than available on the node. VM1 http://prntscr.com/f2w1dj VM2 http://prntscr.com/f2w1ir node http://prntscr.com/f2w1rc As you can see KSM Sharing is still at 0kb and the ram usage of the node is very high.

    Prevent VM to use other IP from subnet

    What I forgot to mention is, that I did found the config for "IP filter" but with enabling this, and configuring a IPSet "ipfilter-net0" to a specific IP form the subnet, does prevent outgooing connctions when the IP is changed on VM. The problem is, that incoming connections still work fine...

    High IO delay on restore

    Hello @ all, I am asking myself why a restore form an NFS storage (1Gbit/s) is causing an IO delay of over 60% even if the disks used on the node are NVMe SSDs that should be minimum 10 times faster then the possible transfer rate over the 1Gbit/s network of the NFS Storage? It also caused a...

    Doubt about optimal network configuration on Hetzner: Combining public and private subnets

    @DerDanilo If u have configured a vmbrX to use a subnet, this would mean that every VM with this bridge coud use any of the IPs in the subnet. This is kind of bad because a "VM client" could change the IP by himself to a different one in the same subnet, right?

    clear unused space on thin-lvm

    So the only way I figured out actually is to change the disks from "virtIO" to "virtIO_scsi" and enable "Discard" option. But how to acomplish that?
