Title:
KVM crashes when attempting to restart migration
Status in QEMU:
Expired
Status in qemu-kvm package in Ubuntu:
Expired
Bug description:
Operations performed:
Sequence to trigger crash:
* Start two kvm systems, one on gerph (primary), one on nbuild2
(listening for incoming migration) - do not use -daemonize
* On gerph, connect to monitor.
* "migrate -d -b tcp:nbuild2:4444"
* "info migrate"
* "migrate_cancel"
* "info migrate"
* "migrate -d -b tcp:nbuild2:4444"
* crashed with assertion:
kvm: block-migration.c:355: flush_blks: Assertion `block_mig_state.read_done
>= 0' failed.
Connection closed by foreign host.
[1]+ Aborted (core dumped) kvm -drive
file=./copy-disk2.img,boot=on -m 4096 -serial mon:telnet::23023,server,nowait
-balloon virtio -vnc :99 -usbdevice tablet -net
nic,macaddr=f6:a6:31:53:89:9a,model=rtl8139,vlan=0 -net tap,vlan=0
Repeating the operations above often dies in different places; just repeat
the cancel and restart the operation. Because the KVM system dies, the
underlying VM is obviously terminated.
