Description Jiri Denemark 2010-10-18 09:49:27 UTC
+++ This bug was initially created as a clone of Bug #630625 +++

Description of problem:

I use "libvirt-0.8.2-7.el5.x86_64" to test again ,I can not migrate successfully with '--tunnelled'.

It very strange ,in a new enviroment with "libvirt-0.8.2-6.el5",I can not migrate successfully as the result of comment 5 .

Issue:At source host,after a long time command will not exits and give a error message .At target host domain "mig" will keep “paused” statu

Steps:
host A:
1.vim /etc/exports
/var/lib/libvirt/images 10.66.93.197/16(rw,no_root_squash)
2. service nfs restart
3. mount 10.66.93.197:/var/lib/libvirt/images/ /mnt

host B:
4. mount 10.66.93.197:/var/lib/libvirt/images/ /mnt
5. cd /mnt
6. virt-install -n mig -r 1024 -f rhel55.img --import
the guest should boot completely.
7. ssh-keygen -t rsa
8. ssh-copy-id -i ~/.ssh/id_rsa.pub root.93.197
9. virsh migrate --live mig qemu+ssh://10.66.93.197/system --tunnelled --p2p

Issue:At source host,after a long time command will not exits and give a error message .At target host domain "mig" will keep “paused” status.

Comment 1 Jiri Denemark 2010-10-18 13:14:21 UTC
libvirt sends 'info chardev' monitor command to qemu but never gets any response since qemu is stuck in read() waiting on migration data from an incoming pipe

Affected package: kvm-83-205.el5
