Hi All,
I saw that you authored the QEMU page for "Multi-process QEMU". (
https://www.qemu.org/docs/master/system/multi-process.html)
I'm interested in this feature, but feel a little confused with the command
line:
+ /usr/bin/qemu-system-x86_64 \
+ -machine x-remote \
+ -device lsi53c895a,id=lsi0 \
+ -drive id=drive_image2,file=/build/ol7-nvme-test-1.qcow2 \
+ -device scsi-hd,id=drive2,drive=drive_image2,bus=lsi0.0,scsi-id=0 \
+ -object x-remote-object,id=robj1,devid=lsi1,fd=4,
(https://lists.gnu.org/archive/html/qemu-devel/2021-01/msg02887.html)
It seems that the man page of qemu command contains no parameter and option
yet for this feature. May I know whether is it still in experimental
stage? And even a few more questions:
- Is "x-remote" a standalone machine type for creating the orchestrator?
- Can each device has a dedicated emulation process or shares one process
for emulating multiple devices?
- Are there more command line examples illustrating the combination of
orchestrator, remote emulation process, memory-backend-memfd and
x-pci-proxy-dev?
Thank you very much
Kind regard
