[libvirt] [PATCH V2 1/2] libxl: Support user-specified <emulator>

This patch is based loosely on David Scott's old patch to do the same https://www.redhat.com/archives/libvir-list/2013-April/msg02119.html Signed-off-by: Jim Fehlig <jfehlig(a)suse.com&gt; --- V2: Check if user-specified emulator is executable. src/libxl/libxl_conf.c | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index 09211f8..715895c 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -705,6 +705,28 @@ libxlMakeDomBuildInfo(virDomainDefPtr def, if (VIR_STRDUP(b_info->u.hvm.boot, bootorder) < 0) goto error; + if (def->emulator) { + if (!virFileExists(def->emulator)) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("emulator '%s' not found"), + def->emulator); + goto error; + } + + if (!virFileIsExecutable(def->emulator)) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("emulator '%s' is not executable"), + def->emulator); + goto error; + } + + VIR_FREE(b_info->device_model); + if (VIR_STRDUP(b_info->device_model, def->emulator) < 0) + goto error; + + b_info->device_model_version = libxlDomainGetEmulatorType(def); + } + if (def->nserials) { if (def->nserials > 1) { virReportError(VIR_ERR_CONFIG_UNSUPPORTED, -- 1.8.4.5
