[Xen-users] What processes on the Dom 0 correspond to a PV guest?
Hi: I am new to Xen. I know that there are many Xen daemons on Dom0,such as xend, xenbus etc. I just curious whether there is a process (or a daemon) on the Dom 0 which is corresponding to a PV guest? Just like in Vmware workstation, every VM is a vmware-vmx.exe process on the host. If there is a process corresponding to each PV guest, what is its name? If not, what will Dom 0 see when I use "xm create" to start a new PV guest? I tried to use ps, and top to watch the processes on Dom0 but find nothing so far. btw: I tested on CentOS 5 with Xen3.1.2 Thanks.

You can use tools like xm top, or xm list to monitor activity of DomUs, you unable to find any processes at Dom0 corresponded to each DomU. VMware Workstation uses Virtual Machine Monitor model, and each virtual machine maintained by one instance of it. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
