Hi! I''m currently preparing to xen installation. In the system that I''m going to set up, there will be a need to copy large amounts of data (therefore I want to avoid using network) from domUs to the dom0 (one way only). Mounting a filesystem RO, when a domU has it mounted RW is probably asking for trouble. Therefore I was thinking about using some remounting protocol similar

Are there people currently managing multiple Dom0''s and making significant use of migration? I''m loking at a potential setup of 16 or so physical systems with perhaps 64 or so virtual systems (DomU''s I suppose Dom0 is also a virtual system if I understand thing correctly, but that''s no twhat I mean here). It seems to me that making heavy use of migration for

Hello, I''m setting up a Xen system since I have diferent choices to create the domU''s partitions: raw partition, lvm, files. I''ve done some tests with hdparm and it all seems to be the same. Can anyone, please, share with me what if the best method. Best regards, Luis _______________________________________________ Xen-users mailing list

Has any one had any success with cow implementation in xen ? I found this somewhere http://www.atconsultancy.nl/cowloop/, has anyone tried it out with xen ? -- regards, Anand _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I had this exact same problem with 2.0.7. I had done a little investigation and found scheduled_work gets called to schedule the shutdown in the user domain kernel, but the shutdown work that gets scheduled never actually gets called. I''m glad someone else is seeing this same problem now :-) Like you, it worked a number of times in a row, then would fail, and it didn''t seem to

Hi all, I have no experience with wireless VoIP. Do you have some quality wireless phones to suggest ? Thanks in advance. Sylvain COUTANT http://www.adviseo.net/

Hi, I have installed debian 3.1 on an Intel Pentium D processor 920 ( including vanderpool.) The installation worked fine and i''m able to start guest-domains. When I try to start the 5.th Guest-Domain, I Get the following error: Error: Device 769 (vbd) could not be connected. Backend device not found. this problem exists still if i have shutdown or destroyed all guests, after

I am considering building a pair of storage servers that will be using CentOS and GFS to share the storage from a Coraid (SATA+Raid) EtherDrive shelf. Has anyone else tried such a setup? Is GFS stable enough to use in a production environment? There is a build of GFS 6.1 at http://rpm.karan.org/el4/csgfs/. Has anyone used this? Is it stable? Will I run into any problems if I use CentOS 3.5

Hi all, We're looking at deploying a small Xen cluster to run some of our smaller applications. I'm curious to get the lists opinions and advice on what's needed. The plan at the moment is to have two or three servers running as the Xen dom0 hosts and two servers running as storage servers. As we're trying to do this on a small scale, there is no means to hook the

Hi list, Here is the idea. I am running a domU out of a partition on a USB drive. I use the other partition to store the domU state. Then I carry this USB key to my office and restore the VM at the point where I left it. Thus I am trying to use xen''s virtualization to carry my desktop on a USB key. I have put up a web page explaining the details and a script to prepare the USB key.

Hello I read about the technology and i found all amazing and great challenger, i like to test and install soon---, for this reason i have some question about this. GFS / CS I see the gfs and cs download into http://bender.it.swin.edu.au/centos-3/ and http://mirrors.csol.org/CentOS/3/csgfs/i386/RPMS/ What are the diference in both packages? Anyone has using this technologies? and example of

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Up until now, I have been using drbd for file custers with great success. Yes, it is a PITA, and sometimes you can get annoying sincronization issues (mostly on lab situations). Now I have been considering giving gnbd (with cs/gfs) a try. Do any of you ever crossed this path ? Any comparisons or comments ? TIA, - -- Rodrigo Barbosa "Quid

Hi there! I am currently setting up a Xen box on 3 VLans, each VLan interface is in a bridge and currently, dom0 is reachable from on of these and is performing great. My only problem is with domU : it can ping anything but it won''t work for TCP and UDP protocol UNLESS I do a manual tcpdump on my vlan interface. Bridges on dom0: xen-vl97 8000.001372529fbf no

Hi everybody, as discussed and agreed at the Cluster Summit we need to split our tree to make life easier in the long run (etc. etc.). We need to decide how we want to do it and there are different approaches to that. I was able to think of 3. There might be more and I might not have taken everything into consideration so comments and ideas are welcome. At this point we haven't really

Thanks John and Chris for your commentary. I''m constantly amazed at what is out there -- projects I didn''t know existed. I think Chris and I are looking for something similiar -- fault tolerant/high-availability over slow/fast links with ease of administration and (ideally) zero downtime. I''d like to virtualize my storage along with my Xen machines. After looking at

Hello all, I''ve been running Xen 2.0x for some few months and have written a simple top(1)-like tool - xenConsole - which continously displays all running domains, along with their CPU-consumption, load averages, percentual CPU-/memory-usage, domain uptimes and so forth. A screenshot probably explains it better than me: http://www.gothix.dk/xenConsole/xcon-0.10b1-ok.PNG It requires

Hi all, I have a little question about a problem i''m experiencing with the new xen 2.0.7: I installed in on a debian box, dom0 starts with no problem, also the domains i copied over from my 2.0.6 box start rightaway BUT: i needed a custom kernel (i want to play with PCI device acces in domU) so i grabbed the 2.0.7 source and compiled the 2.6.11-domU kernel (with the standard config)

We have an Intel VT system, and we have successfully installed Xen 3.0 on it, but we cannot find out how to run Windows as a guest OS. Someone on this mailing list has successfully done it, but did not say how.

Hi, I have configured two machines for testing gfs filesystems. They are attached to a iscsi device and centos versions are: CentOS release 5.4 (Final) Linux node1.fib.upc.es 2.6.18-164.el5 #1 SMP Thu Sep 3 03:33:56 EDT 2009 i686 i686 i386 GNU/Linux The problem is if I try to mount a gfs partition it hangs.

Hi list, I setup on 2 Xen Dom0s drbd/gfs a logical volume, this works as primary/primary so both DomUs will be able to write on them at the same time. But I dont know how to mount them from my domUs, I can see them with fdisk -l. The partition is /dev/xvdb1 SHould I install gfs on domUs and mount them on each as gfs partitions?
