To see true load inside the containers, you'll need an agent running inside the containers that can inspect process details that Dom0 tools don't have easy access to. Pick a monitoring tool of your choosing and use that to monitor both your host and your guests.

smeeb, Depending on what your trying to do as a developer. XEN, VirtualBox, VMware are all Hypervisor engines that are taking the real PC (Ram, HD, CPU, etc). And makeing them virtulized in a "Simulated" mannor. Keeping them abstracted from the real hardware layer of the HOST they are running on. If you writing code that is for the Host, the virtual ...

I had the same problem with debian wheezy 7.8 guests. Installing the wheezy backports kernel 3.16.0-0.bpo.4-amd64 solved it for me. This was on the guests, I didn't touch the host. Add the following line to /etc/apt/sources.list: deb http://ftp.uk.debian.org/debian/ wheezy-backports main Then run apt-get update apt-get -t wheezy-backports install ...

First I would use sshfs. Second up to NFSv3 on Linux NFS is insecure. You can either build a private NFS network or use secure NFSv4.

xenconsoled was not running. After starting it, the problem was gone. Why it was not running is a different question...

Two guesses: 1. Traffic that came in before the DomU xennet was ready to receive. 20℅ is pretty much, though. Do you boot often and have low normal traffic? 2. Broadcast/Multicast Traffic not targeted to the DomU? Is there perhaps an incoming firewall on the DomU?

Try swapping interface configurations in DomU. According to your Dom0 configuration, you should use eth0 for private and eth1 for public IP's in your DomU.

Decide what you want to do: application-independent and more "general" network security done by iptables on the NFS server application-specific security done by nfsd on the NFS server or both. In NFS, you share a directory read-only to a specific client as follows: echo "/mynfs clt.xmpl.com(sync)" >> /etc/exports.d/my-ro.exports exportfs -r

You are not suppose to mount the disk with any filesystem format; In Ubuntu, using gparted I specified the /dev/xvda2 to "Cleared" partition. and running the same command removes the above error.

The answer is no, pygrub does not alter the dom0 grub, all credits goes to PryMar56 from #xen channel on freenode. As I understand correct then pygrub is tool that can extract the boot loader from given image and start that image, so there is no need to specify bootloader or kernel/ramdisk. The image must be of course prepared for this e.g. www.stacklet.com ...

Solved this one, there was an errant POSTROUTING MASQUERADE rule in the iptables unrelated to the OpenVPN installation. I removed the rule with: iptables -t nat -D POSTROUTING 1 Where 1 is the rule number retrieved from service iptables status.
