This thread discusses what you encountered a little bit: http://cboard.cprogramming.com/linux-programming/145015-tried-execute-nx-protected-page-linux-kernel-module-development.html Are these logs in your first screenshot from the Proxmox host itself?

Here is where you check out the time sync: I have found that if the time is not within +-2mins of the Quorate, SSH pipes become inactive. Although I know for a fact this only causes an online node to display as 'offline' with red dot in GUI instead of green. Your issue is interesting. I suspect...

Could you elaborate on how you did that clone operation with dd? I have been trying to accomplish this exact feat, but through a NetCat pipe. When you ran "dd" did you set 'of=' to a real block device or a virtual one?

I don't know anyone who has good things to say about software-based RAID.

Some VMs with GUI do this. If you watch the desktop of your VM when you tell Proxmox to shut it down, it will throw up a box asking something like "Do you wish to shutdown?". The VM will wait for this to be resolved and eventually proxmox will timeout the shutdown command.

Create two VLANs on your switch. Trunk both to the PVE server. you can create vlan-aware bridges in PVE networking tab. Put the LAN VMs on the internal VLAN, and the outside internet VMs on the routable VLAN.

Yes VirtIO is synthetic virtual network adapter, always faster. How do you disable TSO on your networking hardware? Check out this website: https://www.freebsd.org/cgi/man.cgi?query=virtio&sektion=4 I found this there:

It looks like /var/lib/vz/dump is limited to 159Gb, but /var/lib/vz size is 655Gb. You should easily be able to change the size. I don't know how.

yes this

thanks

Sockets hold the processor on the motherboard. Processors have multiple cores. Vcpu = virtual cpu.

Yeah it's going to be difficult. I don't know why you would want to. This arrangement limits scalability.

Has anyone been able to configure HA node fencing using IPMI? I have ipmitools installed on all my nodes, and dedicated IPMI 2.0 interfaces on all my nodes. There are a few problems: Fencing configuration instructions are for PvE versions 3.0 and older (http://pve.proxmox.com/wiki/Fencing)...

Ok yeah I am using version 4.1

Where did you find that XML file? In my proxmox, /etc/pve/cluster.conf does not exist.

where did you find the cluster.conf file?

what do you mean TSO? Why not just stick with e1000 adapter? It looks like you get 12Mbps with that specified instead of the VirtIO, correct? what OS do you select when you create the VM?

This is interesting. you would have to give vmbr1 your static outside global IP address. The one you got from ISP. also confirm correct subnet mask. You will need to define the next-hop gateway in the /etc/network/interfaces configuration for vmbr1. I suspect you will need a default route...

I don't think there is any way to configure authentication using the GUI. I think the NFS server and Client (proxmox) have to have the exact same credentials. The username and user ID have to be identical on both in order for authentication to work. Try that and see if it works.

ok. Another reason I have found my node to randomly restart is because of the 'Watchdog" setting. For example by default I think Watchdog is set to 'reset'. If this is the case, as soon as a VM becomes unresponsive, even if it is not designated as an HA resource, the entire node will restart.
