If any new Xen developers are interested in a simple project to learn Xen development (and also Xen Transcendent Memory), it would be interesting to test this in Xen. AFAIK, the only extensive use of compression is with Transcendent Memory ("tmem"), so learning about tmem would be a useful side-effect. Thanks, Dan

Hello, I have been playing around with Remus on Xen 4.0.1, attempting to fail-over for an HVM domU. I''ve run into some problems that I think could be related to tapdisk2 and its interaction with how one sets up Remus disk replication in the domU config file. A few things I''ve noticed: -The tap:remus:backupHostIP:port|aio:imagePath notation does not work for me, although this

Hi Linux kernel folks and Xen folks -- Effective July 5, I will be resigning from Oracle and "retiring" for a minimum of 12-18 months and probably/hopefully much longer. Between now and July 5, I will be tying up loose ends related to my patches but also using up accrued vacation days. If you have a loose end you''d like to see tied, please let me know ASAP and I will do my

Hi Guys, I''m working with: 1. xen 4.1; 2. dom0 ubuntu kernel 3.2 I''m trying to run remus with disk replication (I can run without disk replication). But I read I need to use tap2 < http://nss.cs.ubc.ca/remus/doc.html>. Well... first I tried to create a pv guest. Then I take this guest.cfg: 1. name = "ubuntu-ha" 2. memory = 256 3. disk =

At last year''s Xen North America Summit in Boston, I gave a talk about memory overcommitment in Xen. I showed that the basic mechanisms for moving memory between domains were already present in Xen and that, with a few scripts, it was possible to roughly load-balance memory between domains. During this effort, I discovered that "ballooning" had a lot of weaknesses, even though

Add ''-C'' (nocow) option to vhd-util create. Btrfs has terrible performance when hosting VM images, even more when the guest in those VM are also using btrfs as file system. One way to mitigate this bad performance is to turn off COW attributes on VM files (since having copy on write for this kind of data is not useful). According to ''chattr'' manpage, NOCOW
