Accessing model attributes in ActiveSupport::Concern module
I have some models which share the same functionality just on other paths.
So I decided to put these methods in a module and set the path in the
model. My problem is that I''m not able to access the attribute in my module.
my model:
class Job < ActiveRecord::Base
include ImageModel
image_dir = "jobs"end
my module:
module ImageModel

Question regarding dropped packets
Hi,
I''ve got a machine that''s hosting a number of virtual machines (58 + the
dom0) and I''m having some weird issues with packet loss and high latency
that happens when ksoftirqd spikes in CPU usage.
The machine itself is CentOS 5 x86_64 running the stock Xen packages
(3.1.2). It''s a dual quad-core w/ hyperthreading, 48 gigs of ram, and

All,
I seem to be experiencing the same problem that Michal Urbanski talked

DomU Guests not shutting down nicely when Dom0 Hypervisor shuts down
I am using Xen 4.6.0-8.el7 on CentOS 7 with 3 Linux DomUs. I did have Xen 4.? on CentOS 6.5 on my previous system. I installed using yum install centos-release-xen.
On shutting down the Hypervisor it used to wait for the DomUs to shut down gracefully (one can take a minute or more), then on starting up again it would restart the DomUs, all nice and controlled.
For some reason the DomUs (CentOS

Xen3 on Etch - Rebooting when 2nd DomU started
Hi All,
Fairly new to Debian and Xen but I have a box running with lots of DomUs
under Xen2 and it is fine.
I have setup a new IBM eServer P4 and loaded Etch and loaded Xen3.
It runs up my first DomU beautifully but when I start my second DomU it
crashes the PC and reboots.
If I comment out the line in /etc/xen/xend-config.sxp
(network-script network-bridge)
It will run 2 DomUs

Inspection of disk snapshots
Greetings,
I have the following typical scenario: given one or more qcow2 base images
I clone them with COW and start the VMs.
At a certain point I'd like to inspect them in order to see their evolution
compared to the known base images. To do so I was thinking about taking a
disk snapshot of each VM and inspect its content through libguestfs (using
it's Python bindings).
Obviously I

Hardware recommendations for XEN
Hi,
I am new to this list. I am planning for hardware upgrade for a new
Linux installation, and I am planning to have it Xen-based. I am
planning to use stable Xen 2.x. This is not going to be a
hyper-performance computer, just a home computer.
So here are few questions I have:
What configurations of CPU/Motherboard/Chipset etc. are already known
not to work, or have problems with Xen? Are

Hyperthreading ON causes OOPS on boot
I just tried to install CentOS (x86_64 4.4 and i386 4.3, not both at
once, when I found the 64bit version didn't boot, I tried the 32bit
version, same result) on a dual Naconda Xeon system. I get an OOPS just
after the IDE info is printed on the screen during boot (this is booting
off the CD during the install phase).
After mucking about with the bios settings (and many reboots later), I

Problems with hyperthreading in Windows HVM
Hi,
I have been trying to get Hyperthreading to work in a Windows HVM on
Xen 4.1.2 as described in ''xmexample.hvm''. I think I have set it up
correctly, but I can''t seem to get it to work. There is not much
documentation on it and most topics are from years ago. I''m curious to
know to whether this functionality is still supposed to work.

hyperthreading and zaptel
My Dell 2800 Dual 64bit Proc. machine came in with hyperthreading enabled. (they call it virtual processor??)
I have been intending for a month to disable it.
Tonight, I rebooted, turned it off, and let the system come up.
zaptel loaded and asterisk loaded, but both of my t1s were red. (it is a TE411P)
/proc/interrupts looked OK, zttest gave OK numbers.
