The 2nd edition of Mastering Proxmox book is soon to be released. https://www.packtpub.com/virtualization-and-cloud/mastering-proxmox-second-edition Proxmox 4.1 along with Open vSwitch, HA, Proxmox Firewall etc. has been covered.

Looks like i found the problem of this issue. Any presence of IPv6 rules causes the syslog to be flooded wuith iptable_cmdlist_restore error. As soon as i disabled all IPv6 rules error disappeared. This also means i cannot use the IPv6 rules at this moment. Is it a known error which will be...

is the latest pve-firewall 2.0-21 not available in subscription level repo?

I should also mention that I have IPv6 enabled in the node and working. Loopback on IPv6 is also enabled.

The version shows pve-firewall: 2.0-18 Running firewall command shows quite a bit of entries for 'create' , 'update' and 'exists'. Not entirely sure if they are errors or normal entries. The very last entry is 'detected changes'.

Hello, Recently i am noticing the following error in one of the Proxmox node syslog: pve-firewall[1869]: status update error: iptables_restore_cmdlist: Try `iptables-restore -h' or 'iptables-restore --help' for more information. I think this error breaking the firewall in this node. Because none...

I do not use HA in this cluster. But i did check if the time in the node itself was correct. They all have NTP enabled and nodes are on same time. Not to toot my own horn by yes there are lot more options in business industry than what people actually realizes. Great product such as Proxmox...

One of my cluster node seem to be going offline and coming back on after couple minutes. But all VM connectivity in the node remains unaffected. It turns red in GUI then turns green.Following is the syslog screenshot right after the node showed offline: What may be causing it to show offline...

Is it cluster configuration? Did you do: service pve-cluster restart service pveproxy restart service pvedaemon restart service pvestatd restart

Can i not use Openvswitch patch port with Proxmox? I entered all necessary configuration in /etc/network/interfaces but after reboot i can see the ports/bridges from GUI but nothing is activated. I can however create the same port/bridge through CLI using ovs-vsctl command and they work. But...

Did you try the test from different KVMs ? Or is it slow only for one VM?

I basically followed the instructions in Sebastian's site. Wanted to follow the exact path. I never clarified with him but i think he meant Kingston KC300 and not Kingston V300. It has been while but i tried quite a few times to squeeze performance out of Kingston V300 but never went higher than...

Looks like i made a mistake in my posting. It should be bus=pci.0,addr=0x18. I posted bus=pci.addr=0x18 My apologies.

I do use smartmon to collect HDD data and pass them to Zabbix. I only collect HDD temp. and Serial # for now. In the zabbix_agent.conf i have the following added: UserParameter=hdd.temp,smartctl -A /dev/$1 | grep -E -i '^[ ]*($2)[ ]' | cut -c88-90 UserParameter=hdd.serial,smartctl -i /dev/$1 |...

This should work for Windows 7 and up: args: -device intel-hda,id=sound5,bus=pci.addr=0x18 -device hda-micro,id=sound5-codec0,bus=sound5.0,cad=0 -device hda-duplex,id=sound5-codec1,bus=sound5.0,cad=1

Any idea why the noVNC console for LXC container shows white cursor only and the login prompt appears only after i hit Enter?

Just wanted to confirm that I am also seeing this issue. But oddly graph is not empty for all nodes in the cluster. In my case there were only 2 nodes that did not show rrd graphs for several days. As soon as i deleted the faulty NFS share graphs showed for these 2 nodes within minutes.

Or may be create a new VM with .raw image for testing purpose.

In my setup i do not use hardware raid. My replicated Gluster is sitting on top of ZFS Raid-Z3 of 35TB usable space in each node. I personally avoid all hardware raid. The raid card used in the nodes are all on JBOD. If you have battery backed RAID controller i believe Writeback is the cache to...

Are the VM you are using all have .qcow2? Have you tried using .raw instead ? If you must use .qcow2 then enable Cache=writethrough for all the disk images then power cycle all the VM. I believe you will see a difference.
