    Cannot hit webUI of application in Container

    by the way I see that your default gateway is outside your subnetwork pve is able to autoadjust this by adding a route to the gateway via the configured device how does the routing table look like on the container ? you should have something like default via 37.187.173.254 dev eth0 onlink...

    Slow io and high io waits

    two remarks: * remember you have to the wkB/s numbers on all your disks to get the throughput of your raid Z2 setup. Or use zpool iostat * during normal VMs use, you have a workflow which is rather a mix of random read and writes, like load from the disk the /bin/ls binary from that sectors...

    VM network freeze

    oh yes, actually this documention is avaible on each installed pve host, so you can replace the intern.lab address with your PVE hostname, so you will have the documentation which matches the installed version of PVE.

    VM network freeze

    @nowrap: if unload / reloading virtionet helps, try to find a way to reproduce the issue Btw if using a load balancer on the VM, it might sense to use the Muliqueue option on the VM nic see https://pve4.intern.lab:8006/pve-docs/chapter-qm.html#qm_network_device

    issues with centos 7 vm

    Most of these freezes happen when the IO wait is too high (the disks are not abled to handle the IO you're asking) check if your IO wait in the host summary is low all the times

See https://www.cyberciti.biz/faq/linux-creating-or-adding-new-network-alias-to-a-network-card-nic/ The question now is why would you want to do that ? If you add private addresses on an interface with is...
