[Qemu-block] ［qemu-block］Can qemu close the image files with guestOS running?

[丁强]

hi all!
I deploy the VMs on filesystem which based on the iscsi LUNs. When the network of san is corrupted occasionally, the filesystem will be remounted read-only by OS with default policy. If you want to remount the filesystem to readwrite, you must shutdown or migrate firstly. Can we recover from this sense without VMs operation, just like vmware without VMCP configuration.

Thanks,
qiang.
