[Xen-devel] Could Xen hyperviosr be able to invoke Linux systemcalls?

2015-08-14 Thread Kun Cheng
Hi all, That might be a dumb question but I just not confident with it. I'm not familiar with Xen's memory management part. Currently I want to add some support (it should cope more with machine memory) to the hyperviosr to assist the management of the above VMs. Now the situation is there're som

[Xen-devel] VM Migration on a NUMA server?

2015-07-31 Thread Kun Cheng
Hi all, I'm sorry for taking your time and I'd like to make an enquery about the status of VM migration support on a NUMA server. Currently It looks like when a vm is migrated only its vcpus are moved to the other node but not its memory. So, is anyone trying to fix that issue? If I want to do it

Let me be more specific, such idea is for the NUMA scheduling as currently xen only migrate vcpus but leave memory at the previous node. Kun Cheng 于2015年7月31日 周五10:32写道: > Hi all, > > I'm sorry for taking your time and I'd like to make an enquery about the > status of VM

[Xen-devel] About evtchn and netfront/netback changes

Hello guys, I'm porting some legacy code initially developed in Xen 4.0 and Linux 2.6 to longterm support kernels 3.2.93 and 4.4.88, and Xen 4.6 or 4.8 (not decided yet but that's not the key issue). My legacy work involves dealing with event channel and xen-netfront/netback drivers. However, I fo
