RE: [Xen-users] Xen Installation on Fedora

["Dustin Henning" <Dustin.Henning@xxxxxxxxxxx>]

The latest Fedora to come with Xen Dom0 support is 8.  This is because it is a separate kernel.  It can be installed with Yum or possibly with a custom installation, however, F8 has obviously been EOL for some time, so you would probably be better off going with the source you have already downloaded.  Once pvops dom0 becomes mainstream, the next version of Fedora may support it, but I don’t know (might ask in a Fedora mailing list).  Otherwise you would be able to compile a custom kernel that supported it (on whatever version of Fedora came with a new enough version of the kernel to support pvops).  In the meantime, it shouldn’t matter which distro you are using if you are downloading the source, as the appropriate Dom0 kernel will be (downloaded and) compiled during compilation of Xen.  Even if it seems like a way older kernel, it should have a lot of newer drivers backported, so don’t panic and not try it  on account of that.  Disclaimer:  I haven’t actually done a Xen from source install (or if I have, it has been a really long time), but I am pretty sure nothing has changed enough to change the accuracy of my (generally generic) statements above.

Subject: [Xen-users] Xen Installation on Fedora

 

Hi,

 

I am new to Xen.  I have few questions in my mind. Can any one of you clarify please.

 

1.       Does Fedora version 10 ,11,12 core has the support for Xen DOM 0 capable kernel support?  Which is the latest Fedora that supports the  Xen DOM 0 kernel support? (Based on this I need to select the correct Fedora version to install for my development environment)

 

2.       Once I install the Fedora, do I need to invoke “yum “ for installing the Virtualization support or the default Fedora installation comes with this.  (MY Hardware has support of Intel VT-x, VT-d and SR-IOV though)

 

3.       I have downloaded latest Xen source  version 3.4.2.  After I build the Xen from the source, where or how does the DOM 0 Linux kernel comes from?  OR is that the Linux (in this case Fedora) that I used for building the Xen becomes the DOM 0 ?  I am confused here.  I read few documents but I could not find how this DOM 0 Linux Guest is created?

 

4.  I am also looking for SR-IOV vf and pf drivers.  Xen-3.4.2 include these?

 

Thanks in advance.

 

regards,

BK.
