Hi, I wanted to use perl Sys::Virt (which uses libvirt) to remotely connect KVM hypervisor. As a start I tried following simple script(KVM.pl) but I am getting following error. First it will ask for authentication which I am providing to it manually then it fails. Do I need to do some configuration on KVM hypervisor before executing this script? Any help is appreciated. bash-3.2$ perl KVM.pl root@10.238.132.125's password: Unable to open connection to qemu+ssh://root@10.238.132.125/system?no_verify=1: End of file while reading data: Warning: Perm: Input/output error8.132.125' (RSA) to the list of known hosts. Can't call method "list_domains" on an undefined value at KVM.pl line 21. bash-3.2$ bash-3.2$ cat KVM.pl use strict; use warnings; use Sys::Virt; use Data::Dump qw(dump); my $user = "root"; my $host = <some_host>; my $uri = "qemu+ssh://root\@$host/system?no_verify=1"; my $vmm; eval { $vmm = Sys::Virt->new(uri => $uri, readonly => 1); }; if ($@) { print "Unable to open connection to $uri: " . $@->message . "\n"; } for my $dom ($vmm->list_domains, $vmm->list_defined_domains) { ## see perldoc Sys::Virt::Domain print "name: ", $dom->get_name, "\n"; print "uuid: ", $dom->get_uuid_string(), "\n"; ## $dom->get_info returns a hash reference dump $dom->get_info; print "\n"; } Regards, Rawat |
