[libvirt] [Libvirt][Sheepdog]How to test network disk support for sheepdog in Libvirt
by harryxiyou 31 Jan '13

31 Jan '13

Hi all, Morita added network disk support for Libvirt, which supported nbd, rbd, sheepdog, and other protocols. Now, i wanna test network disk support for sheepdog solely. I have following questions. Could anyone please give me some suggestions? Thanks in advance. 1, Before this test, whether should i build the environment of sheepdog or other projects (QEMU)? 2, How could i test network disk support of sheepdog in Libvirt? Which steps should i do for it? 3, Network disk support can support online storage management, right? -- Thanks Harry Wei

[libvirt] libvirt error while start vm with VGA passthrough
by mzawdx wang 31 Jan '13

31 Jan '13

http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualiz… I have followed the instructions in the RedHat reference above to the best of my ability to understand them. I add the pci multi-port serial io card through virt-manager and it was indeed entered into the virtual machine's configuration file inside the <devices> tag: <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </hostdev> However, when I try and start the virtual machine I get this error: Error starting domain: internal error Unable to reset PCI device 0000:00:03.0: no FLR, PM reset or bus reset available Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/asyncjob.py", line 44, in cb_wrapper callback(asyncjob, *args, **kwargs) File "/usr/share/virt-manager/virtManager/asyncjob.py", line 65, in tmpcb callback(*args, **kwargs) File "/usr/share/virt-manager/virtManager/domain.py", line 1050, in startup self._backend.create() File "/usr/lib64/python2.6/site-packages/libvirt.py", line 511, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error Unable to reset PCI device 0000:00:03.0: no FLR, PM reset or bus reset available The steps I followed were: 1.

[libvirt] [PATCH] Enforce return check on virAsprintf() calls
by John Ferlan 31 Jan '13

31 Jan '13

Way back when I started making changes for Coverity messages my first set were to a bunch of CHECKED_RETURN errors. In particular virAsprintf() had a few callers that Coverity noted didn't check their return (although some did check if the buffer being printed to was NULL or not). It was suggested at the time as a further patch an ATTRIBUTE_RETURN_CHECK should be added to virAsprintf(), see: https://www.redhat.com/archives/libvir-list/2013-January/msg00120.html This patch does that and fixes two more instances not found by Coverity that failed the check. --- src/util/virutil.h | 3 ++- src/xen/xend_internal.c | 6 ++---- tests/networkxml2conftest.c | 5 +++-- 3 files changed, 7 insertions(+), 7 deletions(-) diff --git a/src/util/virutil.h b/src/util/virutil.h index 5a08c81..c386d24 100644 --- a/src/util/virutil.h +++ b/src/util/virutil.h @@ -200,7 +200,8 @@ int virParseNumber(const char **str); int virParseVersionString(const char *str, unsigned long *version, bool allowMissing); int virAsprintf(char **strp, const char *fmt, ...) - ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_FMT_PRINTF(2, 3); + ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_FMT_PRINTF(2, 3) + ATTRIBUTE_RETURN_CHECK; int virVasprintf(char **strp, const char *fmt, va_list list) ATTRIBUTE_NONNULL(1) ATTRIBUTE_NONNULL(2) ATTRIBUTE_FMT_PRINTF(2, 0); char *virStrncpy(char *dest, const char *src, size_t n, size_t destbytes) diff --git a/src/xen/xend_internal.c b/src/xen/xend_internal.c index b03b7bc..3036cbb 100644 --- a/src/xen/xend_internal.c +++ b/src/xen/xend_internal.c @@ -2738,10 +2738,8 @@ xenDaemonAttachDeviceFlags(virDomainPtr domain, const char *xml, virDevicePCIAddress PCIAddr; PCIAddr = dev->data.hostdev->source.subsys.u.pci; - virAsprintf(&target, "PCI device: %.4x:%.2x:%.2x", PCIAddr.domain, - PCIAddr.bus, PCIAddr.slot); - - if (target == NULL) { + if (virAsprintf(&target, "PCI device: %.4x:%.2x:%.2x", + PCIAddr.domain, PCIAddr.bus, PCIAddr.slot) < 0) { virReportOOMError(); goto cleanup; } diff --git a/tests/networkxml2conftest.c b/tests/networkxml2conftest.c index 3979540..fd24f74 100644 --- a/tests/networkxml2conftest.c +++ b/tests/networkxml2conftest.c @@ -102,8 +102,9 @@ testDnsmasqLeaseFileName(const char *netname) { char *leasefile; - virAsprintf(&leasefile, "/var/lib/libvirt/dnsmasq/%s.leases", - netname); + if (virAsprintf(&leasefile, "/var/lib/libvirt/dnsmasq/%s.leases", + netname) < 0) + return NULL; return leasefile; } -- 1.7.11.7

[libvirt] Libvirt support for windows
by varun bhatnagar 30 Jan '13

30 Jan '13

Hi, I want to use libvirt for windows but when i try to launch virsh it gives an error message saying "*error: invalid argument in transport methods unix, ssh and ext are not supported under Windows"* The version which I downloaded is libvirt-0.8.8.exe. I want to connect to two virtualization techniques --- *Virtualbox* and *VMWare* If libvirt is not supported on windows then is there any other tool or API which supports multiple virtualization technology? Thanks in advance..!!!!

by Stefan Berger 30 Jan '13

30 Jan '13

The following patch series adds initial support for QEMU file descriptor sets implementing support for creating the proper command line. What's missing is currently the monitor support removing the sets once QEMU has started. So these patches are posted for RFC purposes... Regards, Stefan
