[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
by Christoph Höger 01 Aug '08

01 Aug '08

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
by Jim Meyering 01 Aug '08

One good turn deserves another ;-) This also normalizes spacing around the "*" in declarations of vshControl and vshCmd pointers. Of course, this compiles with no warnings and passes "make syntax-check". >From e0db0c0eb4a62eafe1f5790de6d7f9a9d5cb84a0 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Fri, 1 Aug 2008 14:00:20 +0200 Subject: [PATCH] virsh.c: more const-correctness --- src/virsh.c | 266 +++++++++++++++++++++++++++++----------------------------- 1 files changed, 133 insertions(+), 133 deletions(-) diff --git a/src/virsh.c b/src/virsh.c index 620f103..d636301 100644 --- a/src/virsh.c +++ b/src/virsh.c @@ -182,7 +182,7 @@ typedef struct vshCmdOpt { */ typedef struct { const char *name; - int (*handler) (vshControl *, vshCmd *); /* command handler */ + int (*handler) (vshControl *, const vshCmd *); /* command handler */ vshCmdOptDef *opts; /* definition of command options */ vshCmdInfo *info; /* details about command */ } vshCmdDef; @@ -218,35 +218,35 @@ typedef struct __vshControl { static vshCmdDef commands[]; -static void vshError(vshControl * ctl, int doexit, const char *format, ...) +static void vshError(vshControl *ctl, int doexit, const char *format, ...)

[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] Const-correctness in virsh.c
by Richard W.M. Jones 01 Aug '08

01 Aug '08

This rather tedious patch adds const-correctness to the command & info structures in virsh. It's worth noting that it compiles without warning, and the tests still run.

[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. Unfortuntely the place where we *do* delibrately call it is conditionalized on if (network->def->delay So if you set a forward delay of zero, we never explicitly set this on the bridge. Thus the kernel's default setting applies which is 15 seconds. The fix is trivial - just remove the conditional. So previously you could see traffic forwaarding delayed by the kernel for 30 seconds Aug 1 11:34:16 t60wlan kernel: device vnet0 entered promiscuous mode Aug 1 11:34:16 t60wlan kernel: virbr0: port 1(vnet0) entering listening state Aug 1 11:34:31 t60wlan kernel: virbr0: port 1(vnet0) entering learning state Aug 1 11:34:46 t60wlan kernel: virbr0: topology change detected, propagating Aug 1 11:34:46 t60wlan kernel: virbr0: port 1(vnet0) entering forwarding state Now it applies immediately Aug 1 11:40:07 t60wlan kernel: device vnet0 entered promiscuous mode Aug 1 11:40:07 t60wlan kernel: virbr0: port 1(vnet0) entering listening state Aug 1 11:40:07 t60wlan kernel: virbr0: port 1(vnet0) entering learning state Aug 1 11:40:07 t60wlan kernel: virbr0: topology change detected, propagating Aug 1 11:40:07 t60wlan kernel: virbr0: port 1(vnet0) entering forwarding state Daniel Index: src/qemu_driver.c =================================================================== RCS file: /data/cvs/libvirt/src/qemu_driver.c,v retrieving revision 1.98 diff -u -r1.98 qemu_driver.c --- src/qemu_driver.c 30 Jul 2008 09:20:19 -0000 1.98 +++ src/qemu_driver.c 1 Aug 2008 10:46:36 -0000 @@ -1480,8 +1480,7 @@ } - if (network->def->delay && - (err = brSetForwardDelay(driver->brctl, network->def->bridge, network->def->delay))) { + if ((err = brSetForwardDelay(driver->brctl, network->def->bridge, network->def->delay))) { qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, _("failed to set bridge forward delay to %ld"), network->def->delay); -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|

[libvirt] [PATCH]: Add carriage returns to qemudLog
by Chris Lalancette 01 Aug '08

01 Aug '08

Since qemudLog just maps to fprintf(stderr), add carriage returns every where it is used, so it's easier on the eyes while debugging. Signed-off-by: Chris Lalancette <clalance(a)redhat.com>
