During concurrent 80 VM creation, each VM takes two network connections, libvirtd failed to respond.  Neither restart libvirtd nor restart CIMOM helped.  <div><br></div><div>There were 152 vnet bridges found on this RHEL KVM host.  After all the vnet bridges were manually removed, libvirtd responded normally again.</div>

<div><br></div><div>Is there a known issue about the number limit of vnet bridges regarding libvirtd?</div><div><br></div><div>Thank you.</div><div><br></div><div>--Yih</div>
