I copied this pattern from hypervSerializeEprParam(), will fix both
places in next version. Thanks!

...but virBufferCheckError already reports an error, so this is invalid.

[libvirt] [PATCH 1/3] hyperv: Fix hypervInitConnection error reporting

2017-10-03 Thread Ladi Prosek 
"%s is not a Hyper-V server" is not a correct generalization of all possible
error conditions of hypervEnumAndPull. For example:

  $ virsh --connect hyperv://localhost/?transport=http
  Enter username for localhost [administrator]:
  Enter administrator's password for localhost: 
  error: failed to connect to the hypervisor
  error: internal error: localhost is not a Hyper-V server

This commit fixes hypervEnumAndPull to set a meaningful internal error on all
error paths and removes the general virReportError.

The same scenario with the fix:

  $ virsh --connect hyperv://localhost/?transport=http
  Enter username for localhost [administrator]:
  Enter administrator's password for localhost: 
  error: failed to connect to the hypervisor
  error: internal error: Transport error during enumeration: User, password or
  similar was not accepted (26)
