I have installed the Xen kernel successfully on openSUSE 10.2 But my attempts to use Yast to create VMs have not worked as I expected. With the help of a friend I have been able to get VMs working and after quite a lot of fiddling about get all the GNOME graphical desktop stuff into working order. e.g. the Yast sinks back to text mode when installing VMs. Before wasting anyone else's time on this, can we expect the 10.2 version of Yast to be up to the job of fully creating and intalling VMs? After the trouble I had with paravirtualised VMs I am shrinking from attempting the fully virtualised ones (I have an IBM x3500 to try it on). My impression is that the openSUSE 10.2 Xen is also not up to date with the Xen site. I expect that this is inevitable. My ambition is that when I have mastered the use of Xen, I will upgrade all my client sites to using it so that upgrades for version to version of Linux may be less traumatic (for me) than they are now. Is it better to use the source from the Xen site and install VMs by hand using the basic commands vmcreate and so on, or persist with Yast? Can anyone knowledgeable comment on these points? regards John O'Gorman -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

John, do you mean that in the future, we will be able to install a new distribution by just copying one image ? i must say that i've already read some parts about virtualisation, but i thought a 64 bit system was needed for this, and my experiences with 64 bit versions are not that satisfying... jef peeraer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

John,
do you mean that in the future, we will be able to install a new distribution by just copying one image ? That had not been my thought at all. But now that you mention it, I suppose it is possible, provided that you reconfigured network addresses, routing etc. My intention was that while they were running on vm1, I could be installing on vm2. Then when everything tested OK, just switch them over to vm2. The next upgrade would then be on vm1, and so on. i must say that i've already read some parts about virtualisation, but i thought a 64 bit system was needed for this, and my experiences with 64 bit versions are not that satisfying... No it does not need to be 64bit. The machine I am learning this stuff on is 64 bit, but I have installed the 32 bit version of openSUSE 10.2 on it. The Xen stuff does work, but the Yast support for it seems partially broken.

This sounds fine, as far as it goes, but sometime you're going to have to upgrade the host on which vm1 and vm2 run. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I've been using vmware workstation, to ease the transition from one install to another (or, from old hardware to new hardware). So basically, when I make a "big change" of some sort (new install, upgrade, new hardware) the first thing I do after getting the new install working basically, is install vmware. Then, I copy the image of my "old install" and run it as a virtual machine. That way, I can take my time getting the new device/install configured just as I need it, because I have access to the "old one" when I need it.

I don't know for Xen but VMware allow live migration of virtual machine to new esx server hardware. They are also working on seemless migration between esx versions -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
