Current ch driver supports restore only for domains without any network configuration defined. This was because libvirt explicitly passes network fds and CH did not had support to restore with new net FDS. This support has been added recently, https://github.com/cloud-hypervisor/cloud-hypervisor/pull/6402 The changes in this patch series includes moving to socket communication for restore api, create new net fds and pass them via SCM_RIGHTS to CH. New changes in v2: * Reword of few commints * Add version checks in save/restore validations * Add use_timeout in chSocketRecv * Address Praveen Paladugu's comments v1: https://lists.libvirt.org/archives/list/devel@xxxxxxxxxxxxxxxxx/thread/PT77VAI7RF2BUNR2HUIFM46WCP5DVEKV/ Purna Pavan Chandra (8): ch: report response message instead of just code ch: Pass net ids explicitly during vm creation ch: refactor chProcessAddNetworkDevices ch: support poll with -1 in chSocketRecv ch: use monitor socket fd to send restore request ch: refactor virCHMonitorSaveVM ch: support restore with net devices ch: kill CH process if restore fails src/ch/ch_capabilities.c | 6 + src/ch/ch_capabilities.h | 1 + src/ch/ch_driver.c | 29 +++-- src/ch/ch_monitor.c | 62 +++++++---- src/ch/ch_monitor.h | 6 +- src/ch/ch_process.c | 233 +++++++++++++++++++++++++++++++-------- 6 files changed, 254 insertions(+), 83 deletions(-) -- 2.34.1
