Subject: [PATCH] qemu: hotplug: don't overwrite error message in

Since commit f14c37, virDomainConfVMNWFilterTeardown is reporting errors
|
|
|
982648 |
thus any previously reported error gets overwritten.
|
|
|
982648 |
We need to save the errors in qemuDomainAttachNetDevice before calling
|
|
|
982648 |
this function when we are in cleanup code.
