Description

Reported by Daniel Dehennin in the mailing list:

On a ONE 4.2, we just encountered an transiant issue:

[InM][I]: Monitoring host grichka (9)
[InM][I]: Command execution fail: 'if [ -x "/var/tmp/one/im/run_probes" ]; then /var/tmp/one/im/run_probes kvm 9 grichka; else exit 42; fi'
[InM][I]: error: failed to get domain 'one-1547'
[InM][I]: error: Domain not found: no domain with matching name 'one-1547'
[InM][I]: ../../vmm/kvm/poll:70:in `block in get_vm_info': undefined method `[]' for nil:NilClass (NoMethodError)
[InM][I]: from ../../vmm/kvm/poll:68:in `each'
[InM][I]: from ../../vmm/kvm/poll:68:in `get_vm_info'
[InM][I]: from ../../vmm/kvm/poll:35:in `get_all_vm_info'
[InM][I]: from ../../vmm/kvm/poll:401:in `print_all_vm_template'
[InM][I]: from ../../vmm/kvm/poll:440:in `<main>'
[InM][E]: Error executing poll.sh
[InM][I]: ExitCode: 1
[ONE][E]: Error monitoring Host grichka (9): Error executing poll.sh

It looks like something list all the running VM and then call
“get_vm_info” for each one.

This result in an error if the VM disappears in the meantime, because of
a shutdown for example.
