[libvirt] how did libvirt manage Virtual Network?
by Wayne Xia 09 Sep '11

09 Sep '11

Working at the network management, I am a bit confused about the VLAN model in libvirt. in the xml definition, there is a section as following: <devices> <interface type='network'> <source network='default'/> </interface> ... <interface type='network'> <source network='default' portgroup='engineering'/> <target dev='vnet7'/> <mac address="00:11:22:33:44:55"/> <virtualport type='802.1Qbg'> <parameters managerid='11' typeid='1193047' typeidversion='2' instanceid='09b11c53-8b5c-4eeb-8f00-d84eaa0aaa4f'/> </virtualport> </interface> </devices> What is the really meaning of its related parameters of "virtualport"? I want to discover informations such as VLAN id, the switch type( software switch or hardware switch), connecting relationship, but from the xml I can only found "managerid". I am not sure how to map these xml information to those I needed, could I consider managerid as VLAN id, and a portgroup as a specified VLAN group? By the way to use virtualport, what components should I install on Linux? -- Best Regards Wayne Xia mail:xiawenc@linux.vnet.ibm.com tel:86-010-82450803 _______________________________________________________ kvm-cstl mailing list <kvm-cstl(a)lists.linux.ibm.com> To unsubscribe from the list, change your list options or if you have forgotten your list password visit: http://lists.linux.ibm.com/mailman/listinfo/kvm-cstl

[libvirt] [PATCH] Fix URL-escaping for domainDefine
by Philipp Hahn 09 Sep '11

09 Sep '11

'+' in strings get translated to ' ' when editing domains. While xenDaemonDomainCreateXML() did URL-escape the sexpr, xenDaemonDomainDefineXML() did not. Remove the explicit urlencode() in xenDaemonDomainCreateXML() and add the direct encoding calls to xend_op_ext() because it calls xend_post() which uses "Content-Type: application/x-www-form-urlencoded". According to <http://www.w3.org/TR/html4/interact/forms.html#h-17.13.4.1> this requires all parameters to be url-encoded as specified in rfc1738. Notice: virBufferAsprintf(..., "%s=%s", ...) is again replaced by three calls to virBufferURIEncodeString() and virBufferAddChar() because '=' is a "reserved" character, which would get escaped by virBufferURIEncodeString(), which - by the way - escapes anything not c_isalnum().

[libvirt] [PATCH v2] xml: Change virtual file names of xml documents parsed in memory
by Peter Krempa 08 Sep '11

08 Sep '11

While parsing XML strings from memory, the previous convention in libvirt was to set the virtual file name to "domain.xml" or something similar. This could potentialy trick the user into looking for a file named domain.xml on the disk in an attempt to fix the error. This patch changes these filenames to something that can't be as easily confused for a valid filename. Examples of error messages: --------------------------- Error while loading file from disk: 15:07:59.015: 527: error : catchXMLError:709 : /path/to/domain.xml:1: StartTag: invalid element name <domain type='kvm'>< --------------------^ Error while parsing definintion in memory: 15:08:43.581: 525: error : catchXMLError:709 : (domain definition):2: error parsing attribute name <name>vm1</name> --^ Changes to v1: -------------- - Change strings to nicer lowercase versions (suggested by Eric Blake) - Add translation macros - Add example error messages to commit message --- src/conf/domain_conf.c | 2 +- src/security/virt-aa-helper.c | 2 +- tools/virsh.c | 27 ++++++++++++++------------- 3 files changed, 16 insertions(+), 15 deletions(-) diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index 74f8d6a..a4adef0 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -7461,7 +7461,7 @@ virDomainDefParse(const char *xmlStr, xmlDocPtr xml;

[libvirt] [PATCH v4] virsh: Add more human-friendly output of domblkstat command
by Peter Krempa 08 Sep '11

Users of virsh complain that output of the domblkstat command is not intuitive enough. This patch adds explanation of fields returned by this command to the help section for domblkstat and the man page of virsh. Also a switch --human is added for domblkstat that prints the fields with more descriptive texts. https://bugzilla.redhat.com/show_bug.cgi?id=731656 Changes to v3: - Add units to duration values - Add missing write doc/stranslation - Add translation from new api names to legacy names used in previous versions in virsh Changes to v2: - Modify for new fields in virDomainBlockStatsFlags Changes to v1: - Rebase to current head --- tools/virsh.c | 126 +++++++++++++++++++++++++++++++++++++++++++++++------- tools/virsh.pod | 15 ++++++- 2 files changed, 123 insertions(+), 18 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index cf3e816..f281d7a 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -1054,16 +1054,53 @@ cleanup: */ static const vshCmdInfo info_domblkstat[] = { {"help", N_("get device block stats for a domain")}, - {"desc", N_("Get device block stats for a running domain.")}, + {"desc", N_("Get device block stats for a running domain.\n\n" + " Explanation of fields:\n" + " rd_req - count of read operations\n" + " rd_bytes - count of read bytes\n" + " rd_total_times - total time read operations took (ns)\n" + " wr_req - count of write operations\n" + " wr_bytes - count of written bytes\n" + " wr_total_times - total time write operations took (ns)\n" + " flush_operations - count of flush operations\n" + " flush_total_times - total time flush operations took (ns)\n" + " errs - error count")}, {NULL,NULL} };

[libvirt] A question about create image for sheepdog

Hi everyone: I want to build a VM Manage System, and I use libvirt to create and delete VM. But now I has used sheepdog as the disk, but I have to create sheepdog image by hand. If I have a thousand of servers, how can I create the image? I think if I can write a API for create the sheepdog image by call the qemu-img or kvm-img?

Xen PV domU's have no PCI bus. node_device_udev.c calls pci_system_init which looks for /sys/bus/pci. If it does not find /sys/bus/pci (which it won't in a Xen PV domU) it returns unsuccesfully (ENOENT), which libvirt considers fatal. This makes libvirt unusable in this environment, even though there are plenty of valid virtualisation options that work there (LXC, UML, and QEmu spring to mind) https://bugzilla.redhat.com/show_bug.cgi?id=709471 Signed-off-by: Soren Hansen <soren(a)linux2go.dk> --- src/node_device/node_device_udev.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/node_device/node_device_udev.c b/src/node_device/node_device_udev.c index badf241..08ef856 100644 --- a/src/node_device/node_device_udev.c +++ b/src/node_device/node_device_udev.c @@ -1620,7 +1620,7 @@ static int udevDeviceMonitorStartup(int privileged) /* Ignore failure as non-root; udev is not as helpful in that * situation, but a non-privileged user won't benefit much * from udev in the first place. */ - if (privileged || errno != EACCES) { + if (errno != ENOENT && (privileged || errno != EACCES)) { char ebuf[256]; VIR_ERROR(_("Failed to initialize libpciaccess: %s"), virStrerror(pciret, ebuf, sizeof ebuf)); -- 1.7.5.4
