When trying to migrate a VM to another node I get the error, that migration fail because of a RSA mismatch. I can ssh from the original node to the destination node without any problems. Any idea, how to fix the problem? 2017-12-14 18:33:02 # /usr/bin/ssh -e none -o 'BatchMode=yes' -o...

Dear colleagues, I ran into a problem after I changed the IP of the GUI interface. The Web UI was still reachable, but when opening the VNC console, I got an a "failed to connect to server" error. I moved the files: /etc/pve/pve-root-ca.pem /etc/pve/priv/pve-root-ca.key somewhere else and did...

Dear colleagues, I moved to Proxmox 5 in a dev environment and was wondering how to setup the hardware watchdog. On the same hardware running Proxmox 4, a kernel module ipmi_watchdog has been loaded. Now I can only find the following modules. lsmod |grep ipmi ipmi_ssif 24576 0...

I was wondering wether someone managed to build ixgbe drivers for the current Proxmox 4.4. When I try to build the driver, I get an error: make[1]: Entering directory '/usr/src/linux-headers-4.4.62-1-pve' CC [M] /root/ixgbe/ixgbe-5.1.3/src/ixgbe_main.o In file included from...

I just ran into trouble with enabling multicast on the OVSIntPorts. My cluster network uses 2 Intel 10G ports bonded together, 1 Bridge, 2 IntPorts. On the switch side I added a trunk and enabled jumboframes. After setting (according to the wiki) MTU to 8996 ceph cluster stops working, while...

Hello, we are using Proxmox with local storage on a small 3 node cluster. Now we are planning to set up a 4 node cluster with network storage (Ceph), live migration, HA and snapshot functionality. We already have some hardware laying around from dev projects. Now I would like to get some ideas...

I am planing a cluster for a scientific application. I want to use 4 nodes and set up an HA cluster. The nodes have 6 NIC (1GbE) each. Now I want to add redundancy for each network component. The primary focus is to get the cluster network redundant. Right now I do not have a switch, but I have...

Dear collegues, I was really exited about the new ovs integration, as it would further simplify and centralize the administration of cluster installations. So I tried to switch to ovs. I run 2 NICs that form a bond and a ovs_bridge that is connected to the bond. This setting is working so far...

First of all I want to thank the Proxmox guys for this new and really important firewall feature. The interface is straight forward and does exactly what you expect. Especially the cluster-wide settings will save a lot of time. Good job! I have a bunch of firewall scripts around fail2ban on...
