similar to: Some observations on live migration & solution solicitation

Hello, I have now shfited to Centos 5.5, and I am testing live migration between 2 physical hosts with XEN 3.1.2. XEN 3.1.2 (virtualization) is included in centOS 5.5 during the installation phase, so everything is handled by default. A third host with Ubuntu OS serves as the network file system. The three hosts are connected by one D-link gigabit switch (DGS-2205). The downtime of live

hello, I believe I have started guest VM now. Is there any GUI support for guest VM? I tried to "apt-get install gnome", but it doesnot work. My host OS is ubuntu 10.10. 2011/1/18 Ian Tobin <itobin@tidyhosts.com> > Hi, > > > > On debian you need to create or open > > > > /etc/modprobe.d/local-loop > > > > and add > > > > options

I am now testing XEN live migration on two physical hosts with XEN 4.0.1 pvops Ubuntu 10.10 (2.6.35-22). Host A also acts as a NFS server, and Host B acts as a NFS client. When I migrate a guest domain from B to A. The ssh connection experiences a downtime of about 1 minute (the terminal does not react to the keyboard input till about 1 minute later). However, the "sudo xm console" does

Hello, I am a happy user of tinc in multiple environments. It is beautiful - thank you!

I'm assuming you are not asking about post-copy migration, since it is a bit more complicated as the current state if split between the source and destination hosts and none of them can keep running without the other until migration finishes. > * If a

Hello, We have default xen 3.1.2 on centOS 5.5. We now want to upgrade xen 3.1.2 to xen 4.0.1 while using the existing dom0 kernel (2.6.18). I followed the instructions on http://wiki.xensource.com/xenwiki/Xen4.0 hg clone -r RELEASE-4.0.1 http://xenbits.xen.org/xen-4.0-testing.hg cd xen-4.0-testing.hg make xen make tools make stubdom make install-xen make install-tools make install-stubdom And

We are in the process of migrating to new database servers. Our current RAC clusters are running OCFS2 1.2.9 on RHEL 4. Our new servers are running OCFS2 1.6 OEL5. If possible, we would like to minimize the amount of data that needs to move as we migrate to the new servers. We have the following questions: 1. Can we mount an existing OCFS2 1.2 volume on a servers running OCFS2 1.6?

Good Afternoon All. Please forgive me if this is an often-asked question, but ... We're trying to get the ability to have users in the same UNIX group be able to check-in and check-out files from a VSS repository. All users in a defined unix group should be able to copy, edit, and delete any file created by any other user in that group. As most of you probably already know, this works fine

Dear all, Sorry for bothering you but I am having a doubt for a long time and I cannot find a solution for it. I don't know if you can help me but I am doing a research study on Correspondence Analysis and I have been using the package ANACOR. After performing the Correspondence Analysis, I would like to have the factor loadings associated to the first two components. How can I do it?

Hello everyone, Can somebody point where I can find the code where libvirt makes the decision to complete a live migration? I mean, at some point syncronising the VM state, it has to decide that the delta left to be migrate is low enough to achieve downtime 0, so libvirt finishes the migration. This "low enough" must be defined somewhere in the code, but I am unable to find it.

Yes, you don't need to use live migration for this even. The
