[Qemu-devel] Fwd: Qemu Shared memory

2014-06-30 Thread Gary Jordan
Dear developers, I want to design a shared memory for Vm in qemu. So, I also need to design a mechanism to let two vms communicate. Is there already some module in Qemu ? I saw that qemu could support live migration. Can the vm also access the previous machine after migration? Thanks. - Gary

Does Qemu have a VM id allocated for each VM? I did not find this Id in qemu. HOW deos qemu identify each VM, using thread Id or some other identifiers?

If I open two session in a migration operation, how does the qemu know which one should be accepted? I saw there was a ram_list to check, but no id of the guest. 2014-07-02 17:59 GMT-04:00 Eric Blake : > On 07/02/2014 01:20 PM, Gary Jordan wrote: > > Does Qemu have a VM id allocated fo
