i recently study on the remus,and install xen-4.2-unstable on cetos 5.5(x86_64),and the kernel version is
but i met a lot of problem,such as:
1)when using the configure "disk = [ 'tap2:remus:backup:9000|aio:imgpath,xvda,w' ]",after a few minutes,the vm looks just as dead and can NOT log in;
2)i install a centos hvm guest,and run the command "remus <domid>",error message is as follow:
Disk is not replicated: tap:aio:/home/xen/tpl/hvm/base.img,xvda,w
Segmentation fault
3)i install a centos pv guest,the configure file is as follows:
name = "mailserver"
memory = "512"
disk = [ 'tap2:aio:/var/lib/xen/images/vmdisk.img,xvda,w', ]
#disk = [ 'tap2:remus:|aio:/var/lib/xen/images/vmdisk.img,xvda,w', ]
#disk = [ 'tap2:remus:server02:9000|aio:/var/lib/xen/images/vmdisk.img,xvda,w' ]
#vif = [ 'bridge=xenbr0', ]
#vif = [ "type=ioemu,bridge=eth0, mac=00:16:3e:38:9a:ff" ]

it can boot properly.but when run the command "remus <domid>",the error message is as follows:
Disk is not replicated: tap:aio:/var/lib/xen/images/vmdisk.img,xvda,w
WARNING: suspend event channel unavailable, falling back to slow xenstore signalling

i really do not know what to do next and how to address this problem.could anybody tell me how to address them?
What's more,could anybody tell me how to install xen that supports remus properly and how to install PV/HVM domains and the configure file in details ?

I would really pleasure if you could give some advices, thanks lot!
