[PATCH v1 00/21] Run qemu under its own namespace

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Finally. This is full implementation of my RFC:

https://www.redhat.com/archives/libvir-list/2016-November/msg00691.html

The first two patches were posted separately, but since they lack
review I'm sending them here too because they are important for
the feature:

https://www.redhat.com/archives/libvir-list/2016-November/msg01060.html

All of these patches:

a) can be found on my github:
https://github.com/zippy2/libvirt/tree/qemu_container_v2

b) pass my basic testing:
  - run domain with device passthrough
  - device hot(un-)plug (disks, RNGs, chardevs, PCI/USB)

c) seem to add negligible overhead to domain startup process


Michal Privoznik (21):
  qemu: Create hugepage path on per domain basis
  security: Implement virSecurityManagerSetHugepages
  virprocess: Introduce virProcessSetupPrivateMountNS
  virfile: Introduce virFileSetupDev
  virfile: Introduce ACL helpers
  virusb: Introduce virUSBDeviceGetPath
  virscsi: Introduce virSCSIDeviceGetPath
  qemu_cgroup: Expose defaultDeviceACL
  qemu: Spawn qemu under mount namespace
  qemu: Prepare disks when starting a domain
  qemu: Prepare hostdevs when starting a domain
  qemu: Prepare chardevs when starting a domain
  qemu: Prepare TPM when starting a domain
  qemu: Prepare inputs when starting a domain
  qemu: Prepare RNGs when starting a domain
  qemu: Enter the namespace on relabelling
  qemu: Manage /dev entry on disk hotplug
  qemu: Manage /dev entry on hostdev hotplug
  qemu: Manage /dev entry on chardev hotplug
  qemu: Manage /dev entry on RNG hotplug
  qemu: Let users opt-out from containerization
