[libvirt] PATCH: Fix const-ness for virRun/virExec
by Daniel P. Berrange 09 Aug '08

09 Aug '08

The exec() family of UNIX functions have broken const-ness in the argv[] parameter. For inexplicable reasons, I followed this brokeness when originally doing the virRun/virExec functions. So every caller is either using wrong const-ness, or having to cast when calling them. This patch fixes the virRun/virExec API const-ness, so we only need apply a cast at the time we finally call exec() src/iptables.c | 12 ++++++------ src/lxc_driver.c | 2 +- src/openvz_driver.c | 34 +++++++++++++++++----------------- src/qemu_conf.c | 4 ++-- src/qemu_conf.h | 2 +- src/qemu_driver.c | 6 +++--- src/storage_backend.c | 4 ++-- src/storage_backend_disk.c | 4 ++-- src/storage_backend_fs.c | 8 ++++---- src/storage_backend_iscsi.c | 6 +++--- src/storage_backend_logical.c | 12 ++++++------ src/util.c | 16 ++++++++-------- src/util.h | 6 +++--- src/veth.c | 8 ++++---- tests/qemuxml2argvtest.c | 2 +- 15 files changed, 63 insertions(+), 63 deletions(-) Daniel diff -r cc63ab958867 src/iptables.c --- a/src/iptables.c Thu Aug 07 15:00:21 2008 +0100 +++ b/src/iptables.c Thu Aug 07 22:59:08 2008 +0100 @@ -57,7 +57,7 @@ typedef struct { char *rule;

[libvirt] ISCSI Live Migration with LUN backed VMs
by Tim Hughes 07 Aug '08

07 Aug '08

I am using iscsi backed VMs which use a separate LUN for each VM. This is all good until I try to live migrate because the LUN is not logged into on the new machine. Does anyone have a way of handling logging into and out of iscsi luns during the migration ? Tim Hughes mailto:thughes@thegoldfish.org

[libvirt] default networking issues
by Bryan Kearney 07 Aug '08

07 Aug '08

Need some help about where to look next. I am running a Fedora 9 machine, up to date on the releaed rpms. SELinux is permissive, iptables is stopped. I have followed the instructions for NAT forwarding [1]. When I launch a guest in virt manager it uses the default network, and is assigned an IP address in the 192.168.122 space. It can do dns resolution, but can not wget a known website (www.cnn.com) From my host machine, I can ssh into the guest. Where is the next place I should look. Is the fact that I am running in a corporate network causing me issues? Thanks! -- bk [1] http://wiki.libvirt.org/page/Networking#NAT_forwarding_.28aka_.22virtual_ne…

[libvirt] [PATCH] The logic in veth.c that searches for free interface names takes into account
by Dan Smith 07 Aug '08

07 Aug '08

only current devices, but not device names already planned for the other half of a container's device pair. Thus, the search can result in attempting to create a pair of devices such as veth1 and veth1, which obviously does not work. This patch augments the logic to be a little smarter in this regard, and should fix one case where attempting to start a container results in an error message of "unable to create device pair". diff -r 8c5e6387e449 -r 8545f7ac1f0f src/veth.c --- a/src/veth.c Tue Aug 05 16:45:07 2008 +0000 +++ b/src/veth.c Wed Aug 06 08:14:16 2008 -0700 @@ -92,17 +92,18 @@ DEBUG("veth1: %s veth2: %s", veth1, veth2); - if (1 > strlen(veth1)) { + while ((1 > strlen(veth1)) || STREQ(veth1, veth2)) { vethDev = getFreeVethName(veth1, veth1MaxLen, 0); ++vethDev; DEBUG("assigned veth1: %s", veth1); } - if (1 > strlen(veth2)) { + while ((1 > strlen(veth2)) || STREQ(veth1, veth2)) { vethDev = getFreeVethName(veth2, veth2MaxLen, vethDev); DEBUG("assigned veth2: %s", veth2); } + DEBUG("veth1: %s veth2: %s", veth1, veth2); rc = virRun(NULL, (char**)argv, &cmdResult); if (0 == rc) {

Each of those changes has been reviewed by at least two people (see bug-gnulib(a)gnu.org) and most of them address problems also reported on that list, or e.g., on bug-coreutils, bug-m4, etc. However, I suspect some of them have not yet been exercised on RHEL4/5 systems, so test builds there may be interesting. >From e6440820773161436812ccad7eba6d555a8186dd Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Thu, 7 Aug 2008 10:28:22 +0200 Subject: [PATCH] update from gnulib * build-aux/mktempd (rand_bytes, mktempd): * build-aux/useless-if-before-free (FILE): * build-aux/vc-list-files: * gnulib/lib/.cvsignore: * gnulib/lib/Makefile.am: * gnulib/lib/poll.c (poll): * gnulib/lib/stdbool.in.h (_GL_STDBOOL_H, true): * gnulib/lib/stdio-impl.h (fp_, fp_ub): * gnulib/lib/stdio.in.h (vasprintf, obstack_printf) (obstack_vprintf): * gnulib/lib/vasnprintf.c (_GNU_SOURCE, sprintf, IF_LINT, exp) (remainder, scale10_round_decimal_long_double) (scale10_round_decimal_double, pad_ourselves): * gnulib/m4/gnulib-cache.m4: * gnulib/m4/gnulib-common.m4 (gl_MODULE_INDICATOR): * gnulib/m4/gnulib-tool.m4 (gl_LOCAL_DIR, gl_M4_BASE, gl_PO_BASE) (gl_DOC_BASE, gl_TESTS_BASE, gl_WITH_TESTS, gl_LIB, gl_LGPL) (gl_MAKEFILE_NAME, gl_MACRO_PREFIX, gl_PO_DOMAIN, gl_VC_FILES): * gnulib/m4/lock.m4 (gl_LOCK_EARLY_BODY, gl_PREREQ_LOCK) (gl_DISABLE_THREADS): * gnulib/m4/onceonly.m4: * gnulib/m4/posix-shell.m4 (gl_POSIX_SHELL): * gnulib/m4/stdio_h.m4 (gl_STDIO_H_DEFAULTS): * gnulib/tests/test-getaddrinfo.c (ENABLE_DEBUGGING, dbgprintf) (simple): * gnulib/tests/test-stdint.c (UINTMAX_MAX, or): * gnulib/tests/test-vc-list-files-cvs.sh (compare): * gnulib/tests/test-vc-list-files-git.sh (compare): --- build-aux/mktempd | 6 +++- build-aux/useless-if-before-free | 32 +++++++++++++++--------- build-aux/vc-list-files | 5 ++- gnulib/lib/.cvsignore | 12 ++++---- gnulib/lib/Makefile.am | 15 +++++++++++- gnulib/lib/poll.c | 34 ++++++++++++++++++------- gnulib/lib/stdbool.in.h | 6 ++-- gnulib/lib/stdio-impl.h | 4 +- gnulib/lib/stdio.in.h | 20 +++++++++++++++ gnulib/lib/vasnprintf.c | 25 +++++++++++++++---- gnulib/m4/gnulib-cache.m4 | 21 ++++++++++++++- gnulib/m4/gnulib-common.m4 | 9 ++++++- gnulib/m4/gnulib-tool.m4 | 28 ++++++++++++++++++++- gnulib/m4/lock.m4 | 37 +++++++++++++++++++++------- gnulib/m4/onceonly.m4 | 15 +++++++---- gnulib/m4/posix-shell.m4 | 7 +++-- gnulib/m4/stdio_h.m4 | 6 ++++- gnulib/tests/test-getaddrinfo.c | 41 +++++++++++++++++++------------ gnulib/tests/test-stdint.c | 6 ++++- gnulib/tests/test-vc-list-files-cvs.sh | 3 +- gnulib/tests/test-vc-list-files-git.sh | 3 +- 21 files changed, 249 insertions(+), 86 deletions(-)

[libvirt] [PATCH] Install default storage pool
by Cole Robinson 07 Aug '08

07 Aug '08

The attached patch adds a default pool definition to install with libvirt. The pool is a directory pool, hardcoded to use /var/lib/libvirt/images, though this is replaced with %{_localstatedir}/lib/libvirt/images if installing via rpm. Since /var/lib/libvirt/images may not exist if installing from tar.gz, the pool is set not to autostart by default via that method. This patch isn't ready to apply though, since there is one issue I don't know how to solve. We don't want every rpm upgrade to install the default pool, since we don't want the default to continually resurrect itself if a user explicitly deletes it. The default network handles this by checking if libvirtd has been installed. Since libvirtd and virtual network support were introduced around the same time, this makes sense. However for storage, I can't think of any simple check we can make. If we used the same as the default network, all f8 or f9 upgrades wouldn't install the default pool. I can't really think of anything to check, besides maybe doing some sort of time comparison on when /usr/share/libvirt/storage/default.xml was accessed. This code is just hardcoded to always add it. Any ideas? Thanks, Cole

[libvirt] How does virt-manager send shutdown?
by Bryan Kearney 07 Aug '08

07 Aug '08

How does virt-manager send shutdown to guests? Does it depend on if you are running kvm or xen? I have been building images with acpid enabled and acpi=force on the command line. After upgrading to f9 and running kvm my images no longer respond to shutdown. Is there a tweak which I have missed? - bk

[libvirt] [PATCH] storage pool discovery
by David Lively 06 Aug '08

06 Aug '08

Hi - The attached patch implements virConnectDiscoverStoragePools mostly as specified by Daniel Berrange in: http://www.redhat.com/archives/libvir-list/2008-February/msg00107.html Daniel wasn't happy with the interface for this function because it wasn't sufficiently general, so it currently doesn't exist. I've attempted to generalize his proposed interface by changing the "hostname" argument to a "srcSpec" argument, which is intended to be a XML storage pool <source> element. Note that srcSpec is not necessary for some (local) pool types. For example, to discover existing LVM volume groups, there's no need to specify a source: virsh # pool-discover logical While discovering nfs shares requires a <source> document to specify the host to query: virsh # pool-discover netfs "<source><host name='share' /></source>" Currently (i.e., in this patch) I've implemented discovery support only for the "logical" and "netfs" pools. I plan on covering the other types once we've agreed upon the API. While this patch is rather large, the vast majority of it is "generic" (not specific to any particular type of storage pool) code, which I mostly took from Daniel's submission. I could easily break the storage-pool-type-specific pieces into separate patches, but those changes are already segregated into the appropriate storage_backend_ files. * Known Issues * I made the virsh interface take a XML string rather than a filename. I found it convenient, but AFAIK the rest of the commands that take XML take it from a file, so perhaps that should be changed (just let me know what you'd prefer). I realize the description of srcSpec is kind of fuzzy. For instance, for netfs discovery, the <source> must have a <host> element (to specify the host to query), but shouldn't have a <dir> element since the exported dirs are exactly what we're trying to discover in this case. So this really needs to be documented accurately for each storage pool type. (Where?) Finally, there's an underspecification issue. The XML pool descriptions returned are supposed to be usable as valid input to virStoragePoolDefineXML. But these descriptions include some data (pool name, target path) that isn't specified by the discover input or the discovered resources. For now, I'm making up a somewhat arbitrary pool name (logical: VolGroup name, netfs: last component of export path). And I don't even specify <target><path> in the "netfs" discovery output (which means it's not valid input to virStoragePoolDefineXML until a target path is added). Dave

[libvirt] Memory corruption with CVS tip + python
by Chris Lalancette 06 Aug '08

06 Aug '08

All, FYI, I'm running into some memory corruption when using CVS tip and trying to use an older virt-install command. I won't have time to debug this today, so I thought I would mention it on-list in case someone else wants to take a crack at it. My system is an AMD system running RHEL-5.2 x86_64 bits, so it has python-virtinst-0.300.2-8.el5 installed. Basically, I did this: # cvs co libvirt # cd libvirt # ./autogen.sh # make dist >From here, I took the resulting .tar.gz, and dumped it into /usr/src/redhat/SOURCES, and then took the SPEC file from the Fedora 9 sources. I had to modify the very top of it (since RHEL-5 rpmbuild didn't like the macros for whatever reason), but if I read the logic right, I put these flags at the top: %define with_polkit 0 %define with_proxy yes %define with_qemu 0 Then I built and installed a libvirt and libvirt-python RPM with this. Finally, I restarted libvirtd, and then tried to run the following command: [root@amd1 libvirt]# virt-install -n test -f /var/lib/xen/images/test.img -s 10 -r 768 -v -c /var/lib/xen/images/boot.iso -d --vnc Wed, 06 Aug 2008 07:59:10 DEBUG DistroInstaller location is a local file/path: /var/lib/xen/images/boot.iso Starting install... Segmentation fault [root@amd1 libvirt]# It happens every time, so it should be fairly easy to track down. Chris Lalancette

[libvirt] [PATCH]: Fix sexpr generation again
by Chris Lalancette 06 Aug '08

06 Aug '08

DanB pointed out that my sexpr xend_internal patch from yesterday broke one of the regression tests. The problem is that the xenDaemonFormatSxpr{Disk,Net} functions are shared between domain creation time and attaching disk time. Unfortunately, though, Xend expects something different during these two times. During domain creation time, it wants the "(device" in front of the sexpr, while during attach time it does not. To remedy this situation, I added a flag to these two functions to differentiate between these two modes. With this patch in place, all of the regression tests pass.

I'm happy todo the work to at least port the code, but I don't have a OpenVZ enabled machine, so would neeed someone else to actually test if its works :-) Ideally I think we should aim todo a release next week, so I'll look at whatever the state of the OpenVZ code is this coming weekend, and work from that.

[libvirt] [PATCH]: Fix "virsh attach-disk" and "virsh attach-interface"
by Chris Lalancette 05 Aug '08

05 Aug '08

With the recent refactoring of the domain code, plus the changes with the Xend code, a couple of bugs were introduced into the attach-disk and attach-interface functionality. This patch fixes 3 bugs: 1) In xenDaemonAttachDevice(), there is a switch statement to determine which of the xenDaemonFormatSxpr{Disk,Net} functions to call. Unfortunately, the case statements are all missing the corresponding "break", so we always fall-through to the default error case. This patch just adds the appropriate break statements. 2) (minor) In xenDaemonDomainDefineXML (that's a mouthful!), there is a stray "fprintf". This is now converted to a proper virXendError(). 3) xenDaemonFormatSxpr{Disk,Net} were adding an extra (device to the front of the sexpr expressions that xend did not expect (this is Xend on RHEL 5.2). Because of this, the attaches would fail. The patch fixes this by removing the (device from the front, which makes attach-disk and attach-interface work again.

[libvirt] [PATCH]: Rework xenLinuxDomainDeviceID to support more devices
by Chris Lalancette 05 Aug '08

05 Aug '08

Recently upstream Xen added support for having xvd devices > 16. For the most part, this doesn't really concern libvirt, since for things like attach and detach we just pass it through and let xend worry about whether it is supported or not. The one place this breaks down is in the stats collecting code, where we need to figure out the device number so we can go digging in /sys for the statistics. To remedy this, I've re-written xenLinuxDomainDeviceID() to use regular expressions to figure out the device number from the name. The major advantage is that now xenLinuxDomainDeviceID() looks fairly identical to tools/python/xen/util/blkif.py (in the Xen sources), so that adding additional devices in the future should be much easier. It also reduces the size of the code, and, in my opinion, the code complexity. With this patch in place, I was able to get block statistics both on older style devices (/dev/xvda) and on the new, expanded devices (/dev/xvdaa).

[libvirt] libvirt-java storage support and refactoring
by Tóth István 05 Aug '08

05 Aug '08

Hello! This patch contains the following: - The complete storage handling API - Fixing memory leaks in the VirConnect JNI implementation I've written the new classes using a new approach. I've found that libvirt for the most part has a very perdicitble and repetitive API (great design!), and as a result I've found myself copying the same code over and over again. I've decided to make generic JNI functions, that can handle multiple libvirt functions with function pointers. The generic functions are in generic.c and they are used extensively in the new Storage JNI implementation. I'd like to have your input on this architecture, my current plan is to refactor all trivial JNI functions to use these generics, unless there are objections. The positive aspects of the new architecture: - No code duplication, one generic function fix affects all similar functions - Less code The negative aspects: - Ugly syntax (but JNI is ugly enough already) - Easier to make errors in JNI code due to function type casts. I think that the benefits outweigh the negatives, esepecialy when we start cleaning up memory allocation, 64/32 bit cleannes stuff, threading, it will have to be done in one function, instead of 3 or 30 cut'n'pasted ones, scattered in 5 files. best regards István Index: src/org/libvirt/Connect.java =================================================================== RCS file: /data/cvs/libvirt-java/src/org/libvirt/Connect.java,v retrieving revision 1.1 diff -u -r1.1 Connect.java --- src/org/libvirt/Connect.java 18 Jul 2008 14:37:21 -0000 1.1 +++ src/org/libvirt/Connect.java 2 Aug 2008 15:21:11 -0000 @@ -1,5 +1,9 @@ package org.libvirt;

[libvirt] [PATCH] make distclean: remove generated source files

"make distcheck" is failing because two generated source files are left behind. It requires that all generated files be removed.

[libvirt] Question about virbr(dnsmasq)
by Nobuhiro Itou 04 Aug '08

04 Aug '08

Hi all. I have the question about the option of dnsmasq that libvirt sets as a default virtual network. Why does dnsmasq listen to all NICs as specified "--except-interface lo"? And, at the following conditions, the message is output to /var/log/messages. Do you know why it is output? Conditions: 1) Dnsmasq is started by libvirt. And... # ps -ef | grep dnsmasq nobody 5877 5754 0 Jul30 ? 00:00:00 /usr/sbin/dnsmasq --keep-in-foreground --strict-order --bind-interfaces --pid-file --conf-file --listen-address 192.168.122.1 --except-interface lo --dhcp-leasefile=/var/lib/libvirt/dhcp-default.leases --dhcp-range 192.168.122.2,192.168.122.254 2) chenge the network address to '0.0.0.0'. And... # ifconfig eth3 0 up 3) Dnsmasq recieves DHCPINFORM message from other DHCP servers. Message: dnsmasq[5877]: no address range available for DHCP request via eth3 Thank you Nobuhiro Itou

[libvirt] When are volumes 'detected' / refreshed
by Stefan de Konink 04 Aug '08

04 Aug '08

At what time are volumes currently detected on NetFS? I see there is some sort of storage now going on, since deleting files from NFS doesn't delete them from vol-list directly. (If this is fixed in a recent version... I'm sorry to bother) Stefan

[libvirt] fully virtualized xen guest question

Hi, I am running XEN on an debian etch. For clustering purposes I wanted to boot fedora as virtual machine. That works (except for nfs mounts) fine using the paravortualization features. But fully virtulalized guests do not even boot, I do not get any sensefull error message, my config file looks like: <domain type='xen'> <name>werewolf</name> <os> <type>hvm</type> <loader>/usr/lib/xen-3.0.3-1/boot/hvmloader</loader> <kernel>/data/virtual/kernel/kvm1/vmlinuz-2.6.18-6-amd64</kernel> <initrd>/data/virtual/kernel/kvm1/initrd.img-2.6.18-6-amd64</initrd> <cmdline>root=/dev/hda1</cmdline> </os> <memory>524M</memory> <vcpu>1</vcpu> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file'> <source file='/tmp/werewolf.img.plb13810'/> <target dev='hda1' bus='xen'/> </disk> <interface type='bridge'> <source bridge='virbr1'/> </interface> </devices> <features> <acpi/> </features> </domain> <domain type='xen'> <name>werewolf</name> <os> <type>hvm</type> <loader>/usr/lib/xen-3.0.3-1/boot/hvmloader</loader> <kernel>/data/virtual/kernel/kvm1/vmlinuz-2.6.18-6-amd64</kernel> <initrd>/data/virtual/kernel/kvm1/initrd.img-2.6.18-6-amd64</initrd> <cmdline>root=/dev/hda1</cmdline> </os> <memory>524M</memory> <vcpu>1</vcpu> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file'> <source file='/tmp/werewolf.img.plb13810'/> <target dev='hda1' bus='xen'/> </disk> <interface type='bridge'> <source bridge='virbr1'/> </interface> </devices> <features> <acpi/> </features> </domain> all I get when tryin virsh create is: xend_post: error from xen daemon: (xend.err "Error creating domain: (0, 'Error')") Whats wrong?

[libvirt] virsh.c: more const-correctness

[libvirt] PATCH: Support container XML enhancements
by Daniel P. Berrange 01 Aug '08

01 Aug '08

This is something I previously submitted as part of one of the LXC patches, but I figure it makes sense on its own, since OpenVZ needs this now too. This adds two new XML elements to the domain XML format: - An <init> block within <os> allowing specification of the path for a binary to run when starting the container - aka 'init' by any other name. First we also specify that all containers will use an OS type of 'exe' - as in executable - the container equivalent of 'hvm' <os> <type>exe</type> <init>/sbin/init</init> </os> - An <filesystem> element for specifying how the container's filesystem is to be provided. This can actually be useful for full-machine virt too such as KVM which have host filesystem pass-through. There are various ways to configure it: eg to use '/some/directory' as the root filesystem for a container <filesystem type='mount'> <source dir='/some/directory'/> <target dir='/'/> </filesystem> eg to use a template called 'fedora9web' as the root filesystem for a container <filesystem type='template'> <source name='fedora9web'/> <target dir='/'/> </filesystem> eg to use a file containing a filesystem as the root filesystem <filesystem type='file'> <source file='/some/file.img'/> <target dir='/'/> </filesystem> eg to use a disk partition or other block device (eg LVM) containing a filesystem as the root filesystem <filesystem type='block'> <source dev='/dev/VolGroup00/Fedora9Web'/> <target dir='/'/> </filesystem> If setting the root filesystem, the target path will be '/', some container based virt allows the host OS root filesystem to be used in the guest, and merely specify additive mounts at specific locations, eg to override just /home within a container <filesystem type='mount'> <source dir='/some/directory'/> <target dir='/home'/> </filesystem> I believe this should satisfy all the OpenVZ, LXC and Linux-VServer drivers' requirements around filesystems Daniel diff -r 5614da5fe9ef src/domain_conf.c --- a/src/domain_conf.c Fri Jul 25 15:38:46 2008 +0100 +++ b/src/domain_conf.c Tue Jul 29 16:03:38 2008 +0100 @@ -86,6 +86,12 @@ "virtio", "xen") +VIR_ENUM_IMPL(virDomainFS, VIR_DOMAIN_FS_TYPE_LAST, + "mount", + "block", + "file", + "template") + VIR_ENUM_IMPL(virDomainNet, VIR_DOMAIN_NET_TYPE_LAST, "user", "ethernet", @@ -234,6 +240,18 @@ VIR_FREE(def->driverType); virDomainDiskDefFree(def->next); + VIR_FREE(def); +} + +void virDomainFSDefFree(virDomainFSDefPtr def) +{ + if (!def) + return; + + VIR_FREE(def->src); + VIR_FREE(def->dst); + + virDomainFSDefFree(def->next); VIR_FREE(def); } @@ -345,6 +363,7 @@ virDomainGraphicsDefFree(def->graphics); virDomainInputDefFree(def->inputs); virDomainDiskDefFree(def->disks); + virDomainFSDefFree(def->fss); virDomainNetDefFree(def->nets); virDomainChrDefFree(def->serials); virDomainChrDefFree(def->parallels); @@ -355,6 +374,7 @@ VIR_FREE(def->os.type); VIR_FREE(def->os.arch); VIR_FREE(def->os.machine); + VIR_FREE(def->os.init); VIR_FREE(def->os.kernel); VIR_FREE(def->os.initrd); VIR_FREE(def->os.cmdline); @@ -620,6 +640,89 @@ error: virDomainDiskDefFree(def); + def = NULL; + goto cleanup; +} + + +/* Parse the XML definition for a disk + * @param node XML nodeset to parse for disk definition + */ +static virDomainFSDefPtr +virDomainFSDefParseXML(virConnectPtr conn, + xmlNodePtr node) { + virDomainFSDefPtr def; + xmlNodePtr cur; + char *type = NULL; + char *source = NULL; + char *target = NULL; + + if (VIR_ALLOC(def) < 0) { + virDomainReportError(conn, VIR_ERR_NO_MEMORY, NULL); + return NULL; + } + + type = virXMLPropString(node, "type"); + if (type) { + if ((def->type = virDomainFSTypeFromString(type)) < 0) { + virDomainReportError(conn, VIR_ERR_INTERNAL_ERROR, + _("unknown filesystem type '%s'"), type); + goto error; + } + } else { + def->type = VIR_DOMAIN_FS_TYPE_MOUNT; + } + + cur = node->children; + while (cur != NULL) { + if (cur->type == XML_ELEMENT_NODE) { + if ((source == NULL) && + (xmlStrEqual(cur->name, BAD_CAST "source"))) { + + if (def->type == VIR_DOMAIN_FS_TYPE_MOUNT) + source = virXMLPropString(cur, "dir"); + else if (def->type == VIR_DOMAIN_FS_TYPE_FILE) + source = virXMLPropString(cur, "file"); + else if (def->type == VIR_DOMAIN_FS_TYPE_BLOCK) + source = virXMLPropString(cur, "dev"); + else if (def->type == VIR_DOMAIN_FS_TYPE_TEMPLATE) + source = virXMLPropString(cur, "name"); + } else if ((target == NULL) && + (xmlStrEqual(cur->name, BAD_CAST "target"))) { + target = virXMLPropString(cur, "dir"); + } else if (xmlStrEqual(cur->name, BAD_CAST "readonly")) { + def->readonly = 1; + } + } + cur = cur->next; + } + + if (source == NULL) { + virDomainReportError(conn, VIR_ERR_NO_SOURCE, + target ?

[libvirt] PATCH: Fix setting of bridge forward-delay
by Daniel P. Berrange 01 Aug '08

01 Aug '08

The libvirt virtual networking allows setting of the forward-delay parameter. This is the delay the kernel inserts before it starts forwarding traffic when a guest VIF is added to a bridge. The default network config sets this to zero, and previously we had a bug where we accidentally called brSetForwardDelay() based on the STP parameter which was zero, so we did in fact have a forward delay of 0 as desired. Rich then fixed this bug, and thus we no longer accidentally call the brSetForardDelay() method.

[libvirt] libvirt, XEN, bridged network and arp
by Christoph Höger 01 Aug '08

01 Aug '08

Hi, Ive got a severe networking problem over here: When I boot up my machine (debian lenny) using virsh 0.4.4 on an debian etch, a new virtual eth device (something like vif97.0) is assigned to that machine and that device is attached to my bridge virbr1. That is fine. Not so fine is the fact, that no arp packages come over to my bridge for about 5 seconds or so. During that time I can see a lot of arp-who-has on vifXX.0 but nothing on virbr1 so there are no answers and the result is my guest machine not mounting nfs directories on boot. After some time (e.g. after login) networking works fine - but thats definitely too late - I need those directories mounted on boot. Is there a way to fix that?

[libvirt] [PATCH] qemudDomainCreate check if domain is already active
by Guido Günther 01 Aug '08

01 Aug '08

Hi, currently virsh create foo.xml overwrites running domains. In case of qemu this leaves detached qemu processes around and the domain creation fails later on being unable to start other domains afterwards - not nice. Attached patch checks if we already have a running domain by that name and in this case refuses to create a new domain from xml by that name. Probably this check needs to be pushed further upward since this might affect other hypervisors too, haven't checked that though. Cheers, -- Guido

[libvirt] listing domains on Fedora 8 XEN kernel
by Steve Oliphant 01 Aug '08

I am having a problem being able to get domain information in an Fedora 8 XEN environment.The code does not receive an error status on the XEN kernel and does not get any information. The same code running on the non XEN kernel works fine. I am running default configuration files. Is this a known issue? Do I need to tweak the configuration files? Is there anything else I need to do get the code to work on the XEN kernel? Please point me in the right direction. If any other information is required to assist in answering my question, please let me know. Thank you in advance for your help.

[libvirt] what ever happened to the SCSI HBA storage backend?
by David Lively 31 Jul '08

31 Jul '08

Hi Folks - I see Daniel Berrange submitted a SCSI HBA storage backend in March. What ever happened to that? I'd be happy to pick this up if there's more work to do (is there a code base later than the posted patch?) In the longer run, I'm looking towards adding support necessary for FC environments (like multipath). Also, it seems (to my iSCSI-ignorant mind) that iSCSI should be just another flavor of the SCSI driver (kind of like netfs is a flavor of the fs driver ...). Is anyone working on such a refactoring? Thanks, Dave

[libvirt] [PATCH] Detailed XML errors when XML is not well-formed
by Richard W.M. Jones 30 Jul '08

30 Jul '08

This patch changes the implementations lots of functions which parse XML documents, so that if the XML document is not well-formed then we get detailed error messages. The general form of the change is: static void catchXMLError (void *ctx, const char *msg ATTRIBUTE_UNUSED, ...) { // a callback which calls virDomainReportError } virDomainDefPtr virDomainDefParseString(virConnectPtr conn, virCapsPtr caps, const char *xmlStr) { xmlParserCtxtPtr pctxt; pctxt = xmlNewParserCtxt (); pctxt->sax->error = catchXMLError; xml = xmlCtxtReadDoc (pctxt, //...) etc. There are some unavoidable shortcomings: (1) There is no place to stash user pointers during the callback (the suggestively named pctxt->userData field is already used for something else), so we cannot pass the virConnectPtr to the error function. As a result, virterror will store the error in a global variable, and callers will probably not be able to access it. (2) The XML parser routinely produces multiple error messages, and virterror throws away all but the last one. The errors do, however, get printed to stderr. You can test this by using 'virsh define', 'virsh net-define', 'virsh pool-define', etc. on not-well-formed XML files.
