implement suspend to disk for vms the idea is the following:
add a 'suspending' lock halt execution of the vm save the vmstate to a file/disk/etc. hard poweroff the vm (qmp quit) add 'suspended' lock on the next start check for 'suspended' lock resume from saved state the suspending lock prevents any changes to the vm that would prevent a resume (config change, migration, etc) the suspended lock prevents starting a vm that is being suspended changes from v2: * use 2 locks * better error handling/logging * only stop explicitly when not using 'todisk' (savevm-start handles that) * leave prepare state in QemuConfig changes from v1: * rename variable s/stat/state/ * abort if vm is locked with 'backup' lock * remove the lock on error * include date into state file name and make the parameters more explicit * pull out multiple uses of has_lock * add patch for explicitly giving the target storage for the state Dominik Csapak (5): correct comment about size implement suspend to disk for running vms resume suspended vm on start add ability to suspend a vm to disk from the api add statestorage parameter to suspend API PVE/API2/Qemu.pm | 21 +++++++++++- PVE/QemuConfig.pm | 28 +++++++++++----- PVE/QemuServer.pm | 99 +++++++++++++++++++++++++++++++++++++++++++++++++++---- 3 files changed, 132 insertions(+), 16 deletions(-) -- 2.11.0 _______________________________________________ pve-devel mailing list pve-devel@pve.proxmox.com https://pve.proxmox.com/cgi-bin/mailman/listinfo/pve-devel
