Hi all,

I'm a newbie in virtualization. I've started with a new FC6 box and select virtualization when install linux box. Just want to test some basic XEN action before i can get more advanced features.

I've tried to use virt-manager to create a new VM but can't create a new VM.

Maybe I'm did something wrong, so can you guys instruct me howto create a new VM and install OS into that machine. Thanks.

don't use FC6, that's WAY out of date. DO NOT USE IT.

you can use Fedora 15 if you wish, Ubuntu, Mint, or for the enterprise side, try CentOS.

Xen is also largely obsolete in the open source virtualization world since Citrix bought it. You should be looking at KVM instead.

I don't think Citrix owns Xen. They just use it for their Xenserver. Also, news about the kernel supporting Xen has been announced. This makes Xen more appealing. They both have their pro's and con's

Xen is not obsolete. Citrix XenServer is based on Xen and it is Open Source again, which is now called Xen Cloud Platform (XCP). The development of Xen is still very active, however Red Hat has decided not to package it by default anymore. Instead Red Hat is promoting KVM and their standard virtualization solution is based on KVM.

Edit: Xen is the hypervisor and XCP is a complete distribution for cloud computing using Xen Hypervisor.

No sure I didn't mean obsolete in the FC6 sense... just not preferred in general.

Only not preferred by Red Hat actually... They have chosen KVM as the base to build there virtualization solution on.

I don't see any other virtualization living in the mainline 2.6 kernel.

True, but that doesn't mean that KVM is preferred. No matter how much I appreciate the work that the kernel developers do, that doesn't mean that their decisions are the preferences of the people who are using it. I believe that the freedom of choice is the main reason why many of like to use linux. So personally I think you should be a bit more careful about telling what is preferred or not. Because if it is important to use what is preferred, then you should tell to use VMware since it has the biggest install base.

KVM is nice, but if I remember well it is still lacking some features that Xen does have. However when you say that KVM is easier to use than Xen, I must admit that you are right. The reason for that is that it is integrated in the mainline kernel. But according to the latest research I have read, Xen is still used a lot more than KVM. So who decides what is preferred or not?

Thanks all. I'll install FC15 and back to this thread later.
