RE: [Xen-users] Building from Source

["Zhi Wang" <xenlando@xxxxxxxxx>]

I spent many hours to try to build a working Xen from source code. This is what I found for fedora 9.

Build HVM client in Fedora 9

1. When installing fedora core 9, partition the disk using LVM2. Create two virtual group: one for host and the other one for guest. Select the development tools when install the OS.
   
2. yum install mercurial
3. yum install dev86 (for bcc, hvmloader need this)
4. mv /lib/tls /lib/tls.disabled
5. echo "hwcap 0 nosegneg" > /etc/ld.so.conf.d/nosegneg.conf
6. ldconfig
   
7. make world
8. ./install
9. create an initrd by: 
   
1. # depmod 2.6.18-xen
2. # mkinitrd -v -f --with=aacraid --with=sd_mod --with=scsi_mod initrd-2.6.18-xen.img 2.6.18-xen
10. If you will use, VNC's mouse maybe out of sync with the host, in Windows, disable the "Enhance Pointer Precision" option in the mouse configuration

As in steps 4 and 5, I tried to disable the nosegneg warning during Xen start. But it may sometimes still appear. I have no idea why. 

About the Linux distribution, some developers of Xen I happen to know use RHEL 5.2. Maybe you can try CentOS5.2. 

Thanks

"I/O request not ready: 0, pty:0, port: 0, data: 0, count: 0, size: 0".  >Ugh.
