  2. [SOLVED] Changes in pvesh from 5.2 to 5.3

  4. Block Multicast traffic with Bridge configuration?

    A small update. I configured the interface in /etc/network/interfaces and added bridge-mcrouter 0. Restarted the node. After successfully booting the node I can see that the value of /sys/devices/virtual/net/vmbr0/bridge/multicast_router is still 1. Checked multicast traffic on a VM in this...
  5. Block Multicast traffic with Bridge configuration?

    Thank you. This is were we were focusing also. We will try values in /sys/devices/virtual/net/vmbr1/bridge/multicast_snooping /sys/devices/virtual/net/vmbr1/bridge/multicast_router /sys/devices/virtual/net/vmbr1/bridge/multicast_querier etc. It seems that they are integrated in network...
  6. Block Multicast traffic with Bridge configuration?

    Hello, I would like to ask if there is a way to block all multicast traffic coming to specific bridge in a Proxmox node. We can accomplish this at the moment with switch settings and acl. But a node level configuration would be more efficient and "dummy" for all clusters regardless networking...
  7. Meltdown and Spectre Linux Kernel fixes

    It would be helpfull to post some cpu usage metrics here or in another threadm to check the performance impact in various CPUs. Updating all of our clusters, migrating vms and rebooting nodes its a quite time hungry procedure. Do we have an estimation for next kernel? Maybe we can wait if its...

    Is this bug exploitable through a KVM guest using CPU host option? Will it be a patch for PVE 3.X versions?
  11. [SOLVED] Does hyperv running nested on Proxmox?

    Hi all, I did several tests (PVE 4.x) and it seems its not yet fixed. Our clients seem to need this feature lately and we cant do anything. Did anyone accomplished it with PVE 5.x versions? offtopic: Also Docker for windows has problems, but its still in beta.
  12. ceph performance 4node all NVMe 56GBit Ethernet

    If you have some more time to spare, i would suggest to create multiple OSDs per NVMe disk. I doubt ceph at this stage will be able to fully utilize an NVMe disk hosting only one osd. Hope i am wrong. I had very good results in the past with 0.8x ceph versions and handling 2 or 3 osd per disk...
