+Subject: [PATCH] patch qemuMonitorTextGetMigrationStatus to intercept unknown command 'info migrate'
+
+Debian package kvm up to version 72 has not implemented the command 'info migrate'.
+This command interface returns help page of info commands and looks like this:
+
+---8<---
+info version  -- show the version of qemu
+info network  -- show the network state
+info block  -- show the block devices
+info blockstats  -- show block device statistics
+info registers  -- show the cpu registers
+info cpus  -- show infos for each CPU
+info history  -- show the command line history
+info irq  -- show the interrupts statistics (if available)
+info pic  -- show i8259 (PIC) state
+info pci  -- show PCI info
+info tlb  -- show virtual to physical memory mappings
+info mem  -- show the active virtual memory mappings
+info jit  -- show dynamic compiler info
+info kqemu  -- show kqemu information
+info kvm  -- show kvm information
+info usb  -- show guest USB devices
+info usbhost  -- show host USB devices
+info profile  -- show profiling information
+info capture  -- show capture information
+info snapshots  -- show the currently saved VM snapshots
+info pcmcia  -- show guest PCMCIA status
+info mice  -- show which guest mouse is receiving events
+info vnc  -- show the vnc server status
+info name  -- show the current VM name
+info slirp  -- show SLIRP statistics
+info migration  -- show migration information
+--->8---
+
+This patch triggers for 'info migration' in reply to 'info migrate' command
+to savely detect that the command 'info migrate' is not implemented.
