Re: [libvirt] [PATCH] xl: don't output (null) target in domxml-to-native

When converting a domain xml containing a CDROM device without any attached source, don't add a target=(null) to the libxl config disk definition: xen doesn't like it at all and would fail to start the domain. --- src/xenconfig/xen_xl.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/src/xenconfig/xen_xl.c b/src/xenconfig/xen_xl.c index a06983e..db8cbf1 100644 --- a/src/xenconfig/xen_xl.c +++ b/src/xenconfig/xen_xl.c @@ -1068,7 +1068,7 @@ xenFormatXLDisk(virConfValuePtr list, virDomainDiskDefPtr disk) /* devtype */ if (disk->device == VIR_DOMAIN_DISK_DEVICE_CDROM) - virBufferAddLit(&buf, "devtype=cdrom,"); + virBufferAddLit(&buf, "devtype=cdrom");
