NAMESys::Virt::Error − error object for libvirt APIs

---

DESCRIPTIONThe \*(C`Sys::Virt::Error\*(C'\fR class provides an encoding of the libvirt errors. Instances of this object can be thrown by pretty much any of the Sys::Virt APIs.

---

METHODS$err−>stringify Convert the object into string format suitable for printing on a console to inform a user of the error. my $code = $err−>level Return the raw error level represented by this error. One of the ​ERROR LEVEL CONSTANTS my $code = $err−>code Return the raw error code represented by this error. One of the ​ERROR CODE CONSTANTS my $from = $err−>domain Return the error domain raising this error. One of the ERROR ​DOMAIN CONSTANTS my $msg = $err−>message Return an informative message describing the error condition.
