So you should anything like : Errors.Error err = Errors.GetLastError(); MessageBox.Show(err.Message); For the NodeInfo structure, I think the problem is the same that was for DomainInfo, I'll check marshaling. Then respond you with the correct infos. Arnaud PS : can you also put libvirt-list(a)redhat.com in copy of your mails, to keep everyone in the loop ?

[libvirt] [PATCH] [TCK] network: create networks and check for exected results

Derived from the nwfilter test program, this one works with libvirt's networks. It creates networks from provided xml files and checks for expected configuration in iptables, running processes and virsh output using provided data files with commands to execute and the expected results for after creating the network and after tearing it down (*.post.dat). 3 tests are currently not passing due to a bug in libvirt...

[libvirt] [PATCH 0/4] Fix handling of errors with disk labelling on NFS
by Daniel P. Berrange 02 Nov '10

02 Nov '10

The previous commit 06f81c63ebc19cb0e51f9b397991f6d6ae56d090 masked a flaw with handling of errors for NFS disk labels. If you had multiple devices that required labelling, and an disk on root squashing NFS, then when the failure occurred for the NFS file, all further devices would be skipped. The caller would then ignore the error and try to launch the guest anyway, unless there was a stdin_path on NFS. Since NFS error handling was not dealt with in the correct place, this in turn meant that disk hotplug failed with root squashing NFS. All in all a bit of a mess. This tries to clean up the code handling errors closer to the point of occurrance libvirt_private.syms | 1 + qemu/qemu_driver.c | 3 +-- qemu/qemu_monitor_text.c | 28 +++++++++++++++++++--------- security/security_selinux.c | 11 +++++++---- util/storage_file.c | 32 +++++++++++++++++++++++++------- util/storage_file.h | 9 +++++++++ 6 files changed, 62 insertions(+), 22 deletions(-) Daniel

Add a new interface to hostusb.h to add an USB device abstraction to a cgroup whitelist; then use it both when attaching a new USB device and when adding it to the commandline so that the device can be accessed by the QEmu-specific cgroup. --- src/libvirt_private.syms | 1 + src/qemu/qemu_driver.c | 36 ++++++++++++++++++++++++++++++++++++ src/util/hostusb.c | 6 ++++++ src/util/hostusb.h | 4 +++- 4 files changed, 46 insertions(+), 1 deletions(-) diff --git a/src/libvirt_private.syms b/src/libvirt_private.syms index cf06256..0c6f308 100644 --- a/src/libvirt_private.syms +++ b/src/libvirt_private.syms @@ -707,6 +707,7 @@ virMutexUnlock; # usb.h +usbAllowDeviceCgroup; usbDeviceFileIterate; usbDeviceGetBus; usbDeviceGetDevno; diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 1eea3a9..acf319e 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -3505,6 +3505,23 @@ static int qemuSetupCgroup(struct qemud_driver *driver, qemuSetupChardevCgroup, cgroup) < 0) goto cleanup; + + for (i = 0; i < vm->def->nhostdevs; i++) { + virDomainHostdevDefPtr hostdev = vm->def->hostdevs[i]; + usbDevice *usb; + + if (hostdev->mode != VIR_DOMAIN_HOSTDEV_MODE_SUBSYS) + continue; + if (hostdev->source.subsys.type != VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_USB) + continue; + + if ((usb = usbFindDevice(hostdev->source.subsys.u.usb.vendor, + hostdev->source.subsys.u.usb.product)) == NULL) + goto cleanup; + + if (usbAllowDeviceCgroup(usb, cgroup) < 0) + goto cleanup; + } } if ((rc = qemuCgroupControllerActive(driver, VIR_CGROUP_CONTROLLER_MEMORY))) { @@ -8454,6 +8471,25 @@ static int qemudDomainAttachHostUsbDevice(struct qemud_driver *driver, goto error; } + if (qemuCgroupControllerActive(driver, VIR_CGROUP_CONTROLLER_DEVICES)) { + virCgroupPtr cgroup = NULL; + usbDevice *usb; + + if (virCgroupForDomain(driver->cgroup, vm->def->name, &cgroup, 0) !=0 ) { + qemuReportError(VIR_ERR_INTERNAL_ERROR, + _("Unable to find cgroup for %s\n"), + vm->def->name); + goto error; + } + + if ((usb = usbFindDevice(hostdev->source.subsys.u.usb.vendor, + hostdev->source.subsys.u.usb.product)) == NULL) + goto error; + + if (usbAllowDeviceCgroup(usb, cgroup) < 0) + goto error; + } + qemuDomainObjEnterMonitorWithDriver(driver, vm); if (qemuCmdFlags & QEMUD_CMD_FLAG_DEVICE) ret = qemuMonitorAddDevice(priv->mon, devstr); diff --git a/src/util/hostusb.c b/src/util/hostusb.c index 2d6e414..2cbe1fb 100644 --- a/src/util/hostusb.c +++ b/src/util/hostusb.c @@ -225,3 +225,9 @@ int usbDeviceFileIterate(usbDevice *dev, { return (actor)(dev, dev->path, opaque); } + +int usbAllowDeviceCgroup(usbDevice *dev, + virCgroupPtr group) +{ + return virCgroupAllowDevicePath(group, dev->path); +} diff --git a/src/util/hostusb.h b/src/util/hostusb.h index f4a13ca..12269ad 100644 --- a/src/util/hostusb.h +++ b/src/util/hostusb.h @@ -23,6 +23,7 @@ # define __VIR_USB_H__ # include "internal.h" +# include "cgroup.h" typedef struct _usbDevice usbDevice; @@ -48,6 +49,7 @@ typedef int (*usbDeviceFileActor)(usbDevice *dev, int usbDeviceFileIterate(usbDevice *dev, usbDeviceFileActor actor, void *opaque); - +int usbAllowDeviceCgroup(usbDevice *dev, + virCgroupPtr group); #endif /* __VIR_USB_H__ */ -- 1.7.3.2

?Ok, if you are under windows (like me), use GitExtension (http://sourceforge.net/projects/gitextensions/) It works, not perfect, but it works.

I saw your patch file, should I manually apply it to the source code or is there some tools I can use to automatically apply the changes?

Have you tried the NodeInfoStructure I have sended yesterday ?

I made a guess that maybe it was like this: Error err = Errors.SaveLastError(); MessageBox.Show("Get Info error: " + err.Message); It can be compiled but "err.Message" has nothing in it. Did I make a wrong assumption?

So you should anything like : Errors.Error err = Errors.GetLastError(); MessageBox.Show(err.Message); For the NodeInfo structure, I think the problem is the same that was for DomainInfo, I'll check marshaling. Then respond you with the correct infos. Arnaud PS : can you also put libvirt-list(a)redhat.com in copy of your mails, to keep everyone in the loop ?

Code: NodeInfo aNodeInfo = new NodeInfo(); if (Node.GetInfo(con, aNodeInfo) < 0) { //MessageBox.Show("Node Info Error"); MessageBox.Show(Errors.GetLastError().ToString()); return 0f; } I'm sure con != IntPtr.Zero. I tried to use Errors.GetLastError(), it returns int. But I don't know what to do with it. So, any suggestions ?
