Hi! I have a two nodes (A and B), and running vm HostedEngine on host A.
After upgrade host B to latest release CentOS (7.5.1804), i trying to upgrade
host A, but i cannot migrate HostedEngine to host B for next upgrade CentOS.
Another VMs migrated to Host B w/o problems.
In logs on host A i have following lines:
May 17 12:58:16 ovirt-h1 libvirtd: 2018-05-17 07:58:16.728+0000: 3637: error :
virNetClientProgramDispatchError:177 : internal error: cannot execute command
QEMU «cont»: Failed to lock byte 100
May 17 12:58:38 ovirt-h1 journal: ovirt-ha-agent
ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine ERROR Migration failed:
{u'status': {'message': 'Done', 'code': 0}, u'progress': 100}
Please explain me what is my mistake?
P.S I found, that host B have a missmatch in version of packages:
# rpm -aq|grep qemu|sort -n
centos-release-qemu-ev-1.0-2.el7.noarch
ipxe-roms-qemu-20170123-1.git4e85b27.el7_4.1.noarch
libvirt-daemon-driver-qemu-3.9.0-14.el7_5.2.x86_64

qemu-kvm-tools-ev-2.9.0-16.el7_4.14.1.x86_64
Package qemu-kvm-tools-ev has version 2.9.0, while another packages of qemu has
2.10 version.
