[libvirt] [PATCH] qemu: Restore the original states of PCI device when restarting daemon
by Osier Yang 30 Oct '11

30 Oct '11

To support "managed" mode of host PCI device, we record the original states (unbind_from_stub, remove_slot, and reprobe) so that could reattach the device to host with original driver. But there is no XML for theses attrs, and thus after daemon is restarted, we lose the original states. It's easy to reproduce: 1) virsh start domain 2) virsh attach-device dom hostpci.xml (in 'managed' mode) 3) service libvirtd restart 4) virsh destroy domain You will see the device won't be bound to the original driver if there was one. This patch is to solve the problem by introducing internal XML (won't be dumped to user, only dumped to status XML). The XML is: <origstates> <unbind/> <remove_slot/> <reprobe/> </origstates> A new struct "virDomainHostdevOrigStates" is introduced for the XML, and the according members are updated when preparing the PCI device. And function "qemuUpdateActivePciHostdevs" is modified to honor the original states. Use of qemuGetPciHostDeviceList is removed in function "qemuUpdateActivePciHostdevs", and the "managed" value of the device config is honored by the change. This fixes another problem alongside: qemuGetPciHostDeviceList set the device as "managed" force regardless of whether the device is configured as "managed='yes'" or not in XML, which is not right. --- src/conf/domain_conf.c | 79 +++++++++++++++++++++++++++++++++++++++++----- src/conf/domain_conf.h | 26 +++++++++++++++ src/libvirt_private.syms | 6 +++ src/qemu/qemu_hostdev.c | 79 ++++++++++++++++++++++++++++++++++++---------- src/util/pci.c | 36 +++++++++++++++++++++ src/util/pci.h | 9 +++++ 6 files changed, 210 insertions(+), 25 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 5959593..4ccf381 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -59,8 +59,12 @@ verify(VIR_DOMAIN_VIRT_LAST <= 32);

[libvirt] [PATCH] vbox: Add support for VirtualBox 4.1
by Matthias Bolte 29 Oct '11

29 Oct '11

Deal with the incompatible changes in the VirtualBox 4.1 API. INetworkAdapter has its different AttachTo* method replaced by a settable attachmentType property. The maximum number of network adapters is now requestable per chipset type. The OpenMedium method got a bool parameter to request opening a medium under a new IID. --- This patch is compile-tested only and was created by fixing compile errors and looking at the changelog between VirtualBox 4.0 and 4.1. As I currently don't have VirtualBox 4.1 installed and don't have time to upgrade my system and test this, it would be nice if someone with VirtualBox 4.1 at hand could runtime test this patch. The new vbox_CAPI_v4_1.h header file hase been edited out of this patch.

[libvirt] [PATCH] vbox: Support shared folders
by Matthias Bolte 29 Oct '11

29 Oct '11

Shared folders are handled as filesystems and can also be hotplugged. --- Currently this just maps shared folder to a filesystem element with type mount. The filesystem element has an accessmode attribute that is not useful for VirtualBox. Als the target element only has a dir attribute, but VirtualBox shares doen't support that, you can only give them a name. <filesystem type='mount' accessmode='passthrough'> <source dir='/tmp'/> <target dir='foobar'/> <readonly/> </filesystem> I wonder if we should add a shared folder type like this: <filesystem type='sharedfolder'> <source dir='/tmp'/> <target name='foobar'/> <readonly/> </filesystem> Or is this to specific to VirtualBox? VirtualBox 4.0 added the automount option that automatically mounts a shared folder in the guest. On Windows it is mounted to a free drive letter on Linux it's mounted to /media/<prefix>_<shared-folder-name>. The <prefix> is a global configuration option in VirtualBox. I wonder if and how to expose that in libvirt.

[libvirt] [PATCH] xenapi: Improve error reporting in xenapiOpen once again
by Matthias Bolte 29 Oct '11

29 Oct '11

privP->session->error_description is a list and in order to get the complete error message all parts of the list should be concatenated. xenapiSessionErrorHandler does this when its third parameter is NULL. The current code discards all but the first part of the error message resulting in a potentially incomplete error message. This partly reverts 006be75ee214f9b4, that tried to avoid reporting a (null) in the error message. The actual problem is more general in returnErrorFromSession that might return NULL if there is no error. Make sure that returnErrorFromSession return non-NULL always. Also don't skip the last error message part. --- src/xenapi/xenapi_driver.c | 5 +---- src/xenapi/xenapi_utils.c | 4 +++- 2 files changed, 4 insertions(+), 5 deletions(-) diff --git a/src/xenapi/xenapi_driver.c b/src/xenapi/xenapi_driver.c index 97da1d1..77bf82d 100644 --- a/src/xenapi/xenapi_driver.c +++ b/src/xenapi/xenapi_driver.c @@ -193,10 +193,7 @@ xenapiOpen (virConnectPtr conn, virConnectAuthPtr auth, return VIR_DRV_OPEN_SUCCESS; } - xenapiSessionErrorHandler(conn, VIR_ERR_AUTH_FAILED, - *privP->session->error_description != NULL ? - *privP->session->error_description : - _("unknown error")); + xenapiSessionErrorHandler(conn, VIR_ERR_AUTH_FAILED, NULL); error: VIR_FREE(username); diff --git a/src/xenapi/xenapi_utils.c b/src/xenapi/xenapi_utils.c index 342ae5b..79fd946 100644 --- a/src/xenapi/xenapi_utils.c +++ b/src/xenapi/xenapi_utils.c @@ -272,12 +272,14 @@ returnErrorFromSession(xen_session *session) { int i; virBuffer buf = VIR_BUFFER_INITIALIZER; - for (i = 0; i < session->error_description_count - 1; i++) { + for (i = 0; i < session->error_description_count; i++) { if (!i) virBufferEscapeString(&buf, "%s", session->error_description[i]); else virBufferEscapeString(&buf, " : %s", session->error_description[i]); } + if (virBufferUse(&buf) < 1) + virBufferAdd(&buf, _("unknown error"), -1); return virBufferContentAndReset(&buf); } -- 1.7.4.1

[libvirt] [PATCH] macvtap: Fix error return value convention/inconsistencies
by Roopa Prabhu 28 Oct '11

28 Oct '11

From: Roopa Prabhu <roprabhu(a)cisco.com> - changed some return 1's to return -1 - changed if (rc) error checks to if (rc < 0) - fixed some other minor convention violations I might have missed some.
