[CentOS-virt] Xen version

Hi,

We are thinking of using CentOS with XEN in production, but we are facing some issues regarding the 3.0.3 version of the xen hypervisor and windows paravirtualization. The drivers we are using are from here ( http://wiki.xensource.com/xenwiki/XenWindowsGplPv). The solution we found is upgrading to xen 3.4.2, using a strange repository (gitco.de), and everything seems to work. Now the question is: would you recomand using the 3.0.3 kernel provided by CentOS in production and searching for other paravirtualization drivers, or go with 3.4.2? Is this version of the hypervisor stable?
