[libvirt] [PATCH] rpc: Fix getsockopt on Snow Leopard and lower
by Doug Goldstein 11 Oct '13

11 Oct '13

Since 5a468b38b6 we use SOL_LOCAL for the 2nd argument of getsockopt() however Lion added the define SOL_LOCAL set to 0, which is the value to the 2nd argument of getsockopt() for Unix sockets on Mac OS X. So instead of using the define just pass 0 so we restore compatibility with Snow Leopard and Leopard.

[libvirt] [PATCH] esx: Fix floppy.fileName handling in the vmx file parser
by Geoff Hickey 11 Oct '13

11 Oct '13

The vmx file parsing code was reporting errors when parsing floppy.fileName entries if the filename didn't end in .flp. There is no such restriction in ESX; even using the GUI to configure floppy filenames you can specify any arbitrary file with any extension. Fix by changing the vmx parsing code so that it uses the floppy.fileType value to determine whether floppy.fileName refers to a block device or a regular file. --- src/vmx/vmx.c | 26 +++++--------------------- 1 file changed, 5 insertions(+), 21 deletions(-) diff --git a/src/vmx/vmx.c b/src/vmx/vmx.c index 38b7cc0..ffe7e7a 100644 --- a/src/vmx/vmx.c +++ b/src/vmx/vmx.c @@ -2250,27 +2250,18 @@ virVMXParseDisk(virVMXContext *ctx, virDomainXMLOptionPtr xmlopt, virConfPtr con goto cleanup; } } else if (device == VIR_DOMAIN_DISK_DEVICE_FLOPPY) { - if (virFileHasSuffix(fileName, ".flp")) { - if (fileType != NULL) { - if (STRCASENEQ(fileType, "file")) { - virReportError(VIR_ERR_INTERNAL_ERROR, - _("Expecting VMX entry '%s' to be 'file' but " - "found '%s'"), fileType_name, fileType); - goto cleanup; - } - } + if (fileType != NULL && STRCASEEQ(fileType, "device")) { + (*def)->type = VIR_DOMAIN_DISK_TYPE_BLOCK; + (*def)->src = fileName; + fileName = NULL; + } else if (fileType != NULL && STRCASEEQ(fileType, "file")) { (*def)->type = VIR_DOMAIN_DISK_TYPE_FILE; (*def)->src = ctx->parseFileName(fileName, ctx->opaque); if ((*def)->src == NULL) { goto cleanup; } - } else if (fileType != NULL && STRCASEEQ(fileType, "device")) { - (*def)->type = VIR_DOMAIN_DISK_TYPE_BLOCK; - (*def)->src = fileName; - - fileName = NULL; } else { virReportError(VIR_ERR_INTERNAL_ERROR, _("Invalid or not yet handled value '%s' " @@ -3538,13 +3529,6 @@ virVMXFormatFloppy(virVMXContext *ctx, virDomainDiskDefPtr def, virBufferAsprintf(buffer, "floppy%d.fileType = \"file\"\n", unit); if (def->src != NULL) { - if (! virFileHasSuffix(def->src, ".flp")) { - virReportError(VIR_ERR_INTERNAL_ERROR, - _("Image file for floppy '%s' has unsupported " - "suffix, expecting '.flp'"), def->dst); - return -1; - } - fileName = ctx->formatFileName(def->src, ctx->opaque); if (fileName == NULL) { -- 1.8.1.2

[libvirt] [PATCH] qemu: Introduce qemuDomainDefCheckABIStability
by Michal Privoznik 11 Oct '13

11 Oct '13

https://bugzilla.redhat.com/show_bug.cgi?id=994364 Whenever we check for ABI stability, we have new xml (e.g. provided by user, or obtained from snapshot, whatever) which we compare to old xml and see if ABI won't break. However, if the new xml was produced via virDomainGetXMLDesc(..., VIR_DOMAIN_XML_MIGRATABLE) it lacks some devices, e.g. 'pci-root' controller. Hence, the ABI stability check fails even though it is stable. Moreover, we can't simply fix virDomainDefCheckABIStability because removing the correct devices is task for the driver. For instance, qemu driver wants to remove the usb controller too, while LXC driver doesn't. That's why we need special qemu wrapper over virDomainDefCheckABIStability which removes the correct devices from domain XML, produces MIGRATABLE xml and calls the check ABI stability function.

[libvirt] [PATCH] Move virNetDevVPort enum impl into virnetdevvportprofile.c
