similar to: Cloud computing using Xen

HI, guys Recently,I met a problem. Xen''s version: 3.4.3 guest os:redhat 4.8 32bit And xen.independent_wallclock = 1 has been set. The time of guest os change to be fast suddenly, about 2000 second. because the change is too wild, ntp didn''t sync to the ntp server''s time. my application is dependent on the systme time. And this occurs a lot of times. I don''t

I've been involved with getting better data for running Asterisk on the Amazon EC2 cloud computing system. Here are some calculations I've made on costs based on current published prices on Amazon's system. Feel free to tell me that I'm wrong with these calculations - but be specific if you find any problems, as I suspect others may glom onto these figures as gospel and

I have a Xen DomU configuration that was made in the days before libvirt and virt-install. In this configuration I have: vif = [ ''mac=00:16:3e:05:06:01, bridge=xenbr0'', ''mac=00:16:3e:05:06:0a, bridge=xenbr1'' ] and then in xend-config.sxp I define (network-script my-network-bridge) where my-network-bridge is in the scripts directory and looks like this:

I have seen the following kernel panic 5 times today on three different machines, two of which had been stable for months and one of which is a brand new install. We are running the x86_64 xen kernel and userland tools that came in the Xen 3.1.0 tarball from xen.org, on top of scientific linux (redhat clone) 5.1 or 5.2. <Aug/28 12:21 pm>Unable to handle kernel NULL pointer dereference at

I installed 64-bit xen 3.1.0 (from xensource.com tarballs) on three new machines today, using a configuration setup that I''ve used successfully many times before. However, I encountered a new problem. These are Dell Poweredge 1950 servers, by the way. >From lspci 04:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12) 08:00.0 Ethernet

Hello Community, I successfully installed and run xen (xm list and xm info can output appropriately). However, while I was installing domU image by using virt-install -p at domU OS. I encountered an error information" Host does not support virtualization type ''xen'' ". I built xen from source. Some of my friends have the same issue, but if they use pre-build xen, the

Does anyone know if the Xen 3.1.0 kernels as distributed in the "open source" tarballs (x86_64 version) are vulnerable to the recently-announced vulnerability CVE-2007-4573? IF so, is there any plan to release patched tarballs anytime soon? Thanks Steve Timm -- ------------------------------------------------------------------ Steven C.

I have the xensource 3.1.0 x86_64 tarball installed over a RHEL5 clone distribution. The "ethtool" utility only returns the following information: [root@fermigrid5 etc]# ethtool eth0 Settings for eth0: Link detected: yes [root@fermigrid5 etc]# Since I have no vanilla-installed rhel5 machines with which to compare, I am not sure if I am dealing with a bug in the ethtool (whose

Hi: Reading Red Hat''s Website and a printed manual of RH184 (Red Hat Virtualization course) I see that RHEL 5 only supports RHEL 4.5 and RHEL 5 as paravirtualized guests. So I asume this is the same situation for CentOS 5, right? What''s the dependency between Xen versions for paravirtualized guests? I ask this questions because I got this experiences: 1. Running CentOS 5 as

Has anyone yet figured out what it would take to make Xen run on top of the Red Hat Enterprise Linux 6 beta? We are heavily invested in Xen under RHEL5 (actually a redhat clone) distribution, but already the xen kernel they are shipping with update 4 and 5 is shaky and has bugs which they don''t seem to be in a hurry to fix. Basically I am wondering if Redhat 6 is just going to have

I'm starting to use the EC2 cloud (as are others) and noticed that all the available CentOS images seem to be of dubious origin. I think it would further the reputation and popularity of CentOS if it were represented in an official way. In case people aren't aware, when you create an AWS (Amazon Web Services) account there's a management console that shows a list of available images.

I''m running xen 3.1.2 as bastardized by RedHat on a redhat clone operating system. I''m using the xendomains script as it came out of the box to start my domU''s at boot and stop them at shutdown. There are three problems right now: 1) left to its own devices, service xendomains stop attempts to do "xm save" on each of the domU''s. that takes quite a

Hi All, I was wondering if anybody had experience running R on amazon's ec2 "cloud"? More specifically, has anybody created an "amazon machine image" (AMI) for use with it? I was wondering if there was a quantian type image available as an amazon machine image, maybe running debian or ubuntu? It supports open MPI among other libs which is nice. It would be nice to put

Following the recent NYT article about R, I thought this group is not only ready for R but ready to take it one step further. Got models in R?

When I boot from a regular centos kernel, I get this for a mac 00:19:db:e5:91:4f somehow it is getting reversed. Could I have messed something up when I built the kernel?

Hi, I have been able to run 32 bit virtual machines on a 64 bit machine quite nicely with xen3.1 but sometimes when running yum the messages "do_wp_page: bogus page at address 0070d638" and "kernel: VM: killing process yum" and yum just stops working. I also get Kernel Panic. Does anyone have any idea, what could be the probem? Thanks, Ricardo

Asterisk-users, Our two-part tutorial explaining how to use VoIP and Asterisk in Amazon?s Elastic Compute Cloud (EC2) has garnered quite a bit of attention. But due to the time required to complete the many steps needed to get up and running, some of you have asked if it is possible to create a much simpler to install ?pre-built? Asterisk EC2 ?instance.? In short, yes it is. And we?ve

Hi, I (just) posted something similar to this on the fedora-xen list so apologies if some of you see it twice. I''m about to commission a new dom0 host to host multiple dom0 instances for testing purposes. I''m currently trying to decide what platform to use. I''ve previously used FC6 and CentOS5 as Dom0 hosts. I''d like to be able to use Xen 3.2, and I see
