[pve-devel] lasts updates : qemu live migration , missing -machine to target kvm process

[Alexandre DERUMIER]

maybe in migration:


sub prepare {

  $self->{forcemachine} = PVE::QemuServer::qemu_machine_pxe($vmid, $conf);


and

sub qemu_machine_pxe {
    my ($vmid, $conf, $machine) = @_;

    $machine =  PVE::QemuServer::get_current_qemu_machine($vmid) if !$machine;

    foreach my $opt (keys %$conf) {
        next if $opt !~ m/^net(\d+)$/;
        my $net = PVE::QemuServer::parse_net($conf->{$opt});
        next if !$net;
        my $romfile = PVE::QemuServer::vm_mon_cmd_nocheck($vmid, 'qom-get', path => $opt, property => 'romfile');
        return $machine.".pxe" if $romfile =~ m/pxe/;
        last;
    }

}



we return nothing if no pxerom is found

Objet: [pve-devel] lasts updates : qemu live migration , missing -machine to target kvm process

Hi, 

user have reported a problem with migration from proxmox 4.1 (qemu 2.4) to proxmox 4.1 with last updates (qemu 2.5). 
https://forum.proxmox.com/threads/no-online-migration-possible-to-upgraded-cluster-nodes.26158/ 

I thinked it was a qemu problem, 

but looking at generate qemu command line on target host, 


it's missing the 
-machine pc-i440fx-2.4 param. 


It seem to be a regression, but I don't known when it has been introduced.
