hi
Thank you for reply
I read the wiki about the XenSplitDrivers and XenStoreReference ,
and I made a img file and create a vm with the img ,and the conf file is
like the follows
kernel = "/boot/vmlinuz-2.6.16-xenU"
memory = 256
name = "dom1"
vcpus = 1
vif = [ '' ]
disk = [ 'file:/vm/dom1.img,sda1,w' ]
netmask = "255.255.0.0"
gateway = "192.168.150.1"
hostname = "office1"
ip = "192.168.104.4"
root = "/dev/sda1 ro"
there will be a disk in the backend/vbd/domid/virtual-device in the
xenstore,isn`t it?
Does xen support the vm to hotplug another virtual disk ,which is
accessed by dom0?
If it does,what and how does xen deal with the backend and the xenstore?
Are there two elements in the backend/vbd/domid/ in the xenstore?
and what about the frontend in the vm ,are there two frontend in the vm
or just one? how to identify them then?
If it does not ,what should we do to make it work?
Does it need another frontend in the vm or not ?
and how about the backend ?
could you give me some guide ?
Thanks in advance

hi
I try to understand the blkback and blkfront codes,and I am puzzled
about the initialization for both blkback and frontend.
Does the blkback complete the initialization when the dom0 init ?and
when does the frontend in guestOS try to connet with the blkback in the
dom0? and how does the frontend do? how does the frontend register the
relative entryes in the xenstore in the dom0?
I am really puzzled ,could anyone help me?
