Re: [Xen-users] Xen 3.4 Qcow based Copy of write overlay for Centos 	bas 
| Hello Fajar 
 First of all thanks for your quick reply.
 
 After reading the link given by you, i came in below conclusion.
 
 1. Xen 3.4 does not have tap poll on aio support. I have to apply the updated patch and build it again.
 
 2. After patch is implemented , i will be able to run PV HVM guests using qcow overlay. mentioned in my earlier.
 
 3. This patch is already built in RHEL 5.4. (xen-3.0.3-86.el5
)
 
 Is above statements are correct understanding of mine.
 
 It will be good if you confirm me.
 
 Arun
