[libvirt] [libvirt-php] bug in libvirt_domain_change_vcpus()
by Olivier Doucet 10 Sep '13

10 Sep '13

Hello everyone, I think there is a bug in the current implementation of function libvirt_domain_change_vcpu(). When using this function (with second parameter = 2), I have the following error : Error setting maxvcpus=2: (domain_definition):8: Specification mandate value for attribute curre <vcpu>2</vcpu> --^ If I'm right, the equivalent with 'virsh' binary is 'setvcpus', and this is working. If I look into source code (http://libvirt.org/git/?p=libvirt-php.git;a=blob;f=src/libvirt-php.c;h=7ce2…) it seems this operation is done by rewriting the whole XML. I think we should use instead C function virDomainSetVcpus http://libvirt.org/html/libvirt-libvirt.html#virDomainSetVcpus What do you think ? Olivier

[libvirt] [PATCH] qemu: Fix connectGetType() API
by Michal Novotny 10 Sep '13

10 Sep '13

This patch fixes qemuConnectGetType() API function to return KVM if appropriate, i.e. when /dev/kvm exists as the KVM module is loaded. No further check is being done so it's merely showing the possibility that KVM virtualization is available on the host however we don't have any guest information (as it's connection-only related) so we cannot sure we can use KVM. This can be useful to identify we have KVM (Virt Support) available on the host if host and guest archs are the same. Testing: Done using a simple application with C source code below. [before patch applied]$ ./test Hypervisor type: QEMU [after patch applied]$ ./test Hypervisor type: KVM $ Testing C code: int main() { virConnectPtr conn = NULL; conn = virConnectOpen("qemu:///system"); if (!conn) return 1; printf("Hypervisor type: %s\n", virConnectGetType(conn)); virConnectClose(conn); return 0; } Compiled on F-17 x86_64 host using: gcc -o test test.c -lvirt Signed-off-by: Michal Novotny <minovotn(a)redhat.com> --- src/qemu/qemu_driver.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 9b5d126..b770967 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1132,6 +1132,16 @@ static const char *qemuConnectGetType(virConnectPtr conn ATTRIBUTE_UNUSED) { if (virConnectGetTypeEnsureACL(conn) < 0) return NULL; + /* + * If KVM is available for the host architecture then report KVM support. + * This approach merely shows it is possible to have KVM support as module is + * loaded however if you select different architecture, e.g. ARM on x86_64 host, + * the KVM option will not be available as there is no KVM virtualization + * support for ARM architecture that could be running on top of x86_64 host. + */ + if (access("/dev/kvm", F_OK) == 0) + return "KVM"; + return "QEMU"; } -- 1.7.11.7

[libvirt] [PATCH 0/4] build: use subdir-objects
by Eric Blake 10 Sep '13

10 Sep '13

Automake 1.14 is annoyingly loud about warning that the future automake 2.0 will turn on subdir-objects by default. Since automake 1.9 also supports subdir-objects, the best course of action is to enable the feature. But we have to fix some problems before doing so. Also, I noticed some issues with .x files while searching for places that needed fixing.

[libvirt] [PATCH V3] Use loop-control to allocate loop device.
by Ian Main 09 Sep '13

09 Sep '13

This patch changes virFileLoopDeviceOpen() to use the new loop-control device to allocate a new loop device. If this behavior is unsupported we fall back to the previous method of searching /dev for a free device. With this patch you can start as many image based LXC domains as you like (well almost). Fixes bug https://bugzilla.redhat.com/show_bug.cgi?id=995543 V2: - Modified to use a dedicated error return for loop-control allocation function. - Only do fallback if /dev/loop-control does not exist, otherwise return error.

[libvirt] [PATCHv2] qemu: don't leak vm on failure

Failure to attach to a domain during 'virsh qemu-attach' left the list of domains in an odd state: $ virsh qemu-attach 4176 error: An error occurred, but the cause is unknown $ virsh list --all Id Name State ---------------------------------------------------- 2 foo shut off $ virsh qemu-attach 4176 error: Requested operation is not valid: domain is already active as 'foo' $ virsh undefine foo error: Failed to undefine domain foo error: Requested operation is not valid: cannot undefine transient domain $ virsh shutdown foo error: Failed to shutdown domain foo error: invalid argument: monitor must not be NULL It all stems from leaving the list of domains unmodified on the initial failure; we should follow the lead of createXML which removes vm on failure (the actual initial failure still needs to be fixed in a later patch, but at least this patch gets us to the point where we aren't getting stuck with an unremovable "shut off" transient domain). While investigating, I also found a leak in qemuDomainCreateXML; the two functions should behave similarly. Note that there are still two unusual paths: if dom is not allocated, the user will see an OOM error even though the vm remains registered (but oom errors already indicate tricky cleanup); and if the vm starts and then quits again all before the job ends, it is possible to return a non-NULL dom even though the dom will no longer be useful for anything (but this at least lets the user know their short-lived vm ran). * src/qemu/qemu_driver.c (qemuDomainCreateXML): Don't leak vm on failure to obtain job.

[libvirt] [PATCHv2 RESEND 0/5] Handling of undefine and redefine snapshots with VirtualBox 4.2
by Manuel VIVES 09 Sep '13

09 Sep '13

Hi, This is a serie of patches in order to support undefining and redefining snapshots with VirtualBox 4.2. The serie of patches is rather big, and adds among other things some utility functions unrelated to VirtualBox in patches 1 & 2. The code review could be done in several parts: e.g. patches 1 & 2 separately to validate the utility functions. This 2nd version brings a different function for string replacement, because of the license problem with the first one. The VirtualBox API provides only high level operations to manipulate snapshots, so it not possible to support flags like VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE and VIR_DOMAIN_SNAPSHOT_DELETE_METADATA_ONLY with only API calls. Following an IRC talk with Eric Blake, the decision was taken to emulate these behaviours by manipulating directly the .vbox XML files. The first two patches are some util methods for handling uuid and strings that will be used after. The third patch brings more details in the snapshot XML returned by libvirt. We will need those modifications in order to redefine the snapshots. The fourth patch brings the support of the VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE and VIR_DOMAIN_SNAPSHOT_CREATE_CURRENT flags in virDomainSnapshotCreateXML. The fifth and last patch brings the support of the VIR_DOMAIN_SNAPSHOT_DELETE_METADATA_ONLY flag in virDomainSnapshotDelete. The patches are only for Virtualbox 4.2 Regards, Manuel VIVES Manuel VIVES (5): viruuid.h/c: Util method for finding uuid patterns in some strings virstring.h/c: Util method for making some find and replace in strings vbox_tmpl.c: Better XML description for snapshots vbox_tmpl.c: Patch for redefining snapshots vbox_tmpl.c: Add methods for undefining snapshots src/conf/domain_conf.c | 20 +- src/libvirt_private.syms | 2 + src/util/virstring.c | 48 ++ src/util/virstring.h | 2 + src/util/viruuid.c | 79 ++ src/util/viruuid.h | 1 + src/vbox/vbox_tmpl.c | 1846 +++++++++++++++++++++++++++++++++++++++++++--- 7 files changed, 1878 insertions(+), 120 deletions(-) -- 1.7.10.4

[libvirt] [PATCH v3 0/8] Support qemu-system-arm vexpress-a9
by Cole Robinson 09 Sep '13

09 Sep '13

This series adds the bits needed to kick of a qemu-system-arm -machine vexpress-a9 guest. vexpress-a15 likely works as well but is untested. Patches 1-2 are related bugfixes/improvements. Patch 6 adds disk bus=sd, which is often the only way to specify storage for ARM boards. Patch 8 adds virtio-mmio address support, which enables virtio for ARM vexpress machine types. The rest are mostly about fixing CLI generations. Unfortunately qemu ARM boards don't quite work like x86 where we can mix and match devices, so -device is out of the picture (for non-virtio), meaning we have to fall back to CLI infrastrucure like -net nic and -serial. v3: Rebased series Add qemu.conf nographics_allow_host_audio for patch #1 Drop domain_conf.c default memballoon handling in patch #2, not #3 Cole Robinson (8): qemu: Set QEMU_AUDIO_DRV=none with -nographic domain_conf: Add default memballoon in PostParse callbacks qemu: Don't add default memballoon device on ARM qemu: Fix specifying char devs for ARM qemu: Don't try

[libvirt] [PATCHv5 0/5] Introduce API to query IP addresses for given domain
by Nehal J Wani 08 Sep '13

08 Sep '13

This feature has been requested for a very long time. Since qemu guest agent gives us reliable results, now the wait is over. The RFC was first proposed by Michal Privoznik: http://www.redhat.com/archives/libvir-list/2012-February/msg00437.html A patch was submitted, using structs: https://www.redhat.com/archives/libvir-list/2012-June/msg00220.html Another patch was submitted, using XML: https://www.redhat.com/archives/libvir-list/2012-June/msg00904.html Neither of the patches were accepted, probably due to lack of extensibility and usability. Hence, we thought of using virTypedParameters for reporting list of interfaces along with their MAC address and IP addresses. The RFC can be found here: https://www.redhat.com/archives/libvir-list/2013-July/msg00084.html The idea of extensibility was rejected and rendered out of scope of libvirt. Hence, we were back to structs. This API is called virDomainInterfaceAddresses which returns a dynamically allocated array of virDomainInterface struct. The great disadvantage is once this gets released, it's written in stone and we cannot change or add an item into it. The API supports two methods: * Return information (list of all associated interfaces with MAC address and IP addresses) of all of the domain interfaces by default (if no interface name is provided) * Return information for the specified interface (if an interface name is provided) v5: * s/virDomainInterfacesAddresses/virDomainInterfaceAddresses. * Case for IP aliasing handled using virHashTable. * New test cases added, involving multiple and 0 IP addresse(s) per interface. * IP prefix changed from int to unsigned int. * Changes to practice libvirt habits. v4: * Various style nits, indentation errors, memory leaks fixed. * https://www.redhat.com/archives/libvir-list/2013-August/msg01265.html v3: * Upper bounds to number of interfaces and addresses per interface introduced. * Change from array of structs to array of pointers * ifaces_count moved from function argument to return value * Changes in variable names * Test cases added for qemuAgentGetInterfaces. * https://www.redhat.com/archives/libvir-list/2013-August/msg01215.html v2: * Logical errors, memory leaks and few other errors fixed. * https://www.redhat.com/archives/libvir-list/2013-August/msg00631.html v1: * http://www.redhat.com/archives/libvir-list/2013-July/msg01553.html Nehal J Wani (5): domifaddr: Implement the public APIs domifaddr: Implement the remote protocol domifaddr: Implement the API for qemu domifaddr: Add virsh support domifaddr: Expose python binding daemon/remote.c | 131 +++++++++++++++++++++++++++ examples/python/Makefile.am | 2 +- examples/python/README | 1 + examples/python/domipaddrs.py | 50 +++++++++++ include/libvirt/libvirt.h.in | 32 +++++++ python/generator.py | 3 + python/libvirt-override-api.xml | 8 +- python/libvirt-override.c | 111 +++++++++++++++++++++++ src/driver.h | 6 ++ src/libvirt.c | 115 ++++++++++++++++++++++++ src/libvirt_public.syms | 6 ++ src/qemu/qemu_agent.c | 193 ++++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_agent.h | 3 + src/qemu/qemu_driver.c | 55 ++++++++++++ src/remote/remote_driver.c | 99 +++++++++++++++++++++ src/remote/remote_protocol.x | 40 ++++++++- src/remote_protocol-structs | 24 +++++ tests/qemuagenttest.c | 149 +++++++++++++++++++++++++++++++ tools/virsh-domain-monitor.c | 119 +++++++++++++++++++++++++ tools/virsh.pod | 11 +++ 20 files changed, 1155 insertions(+), 3 deletions(-) create mode 100755 examples/python/domipaddrs.py -- 1.7.11.7

I'm posting patches that I have so far to start reviews, but need to write still more patches as I still haven't succeeded at attaching. I also need to add a patch to the testsuite to cover the command line that I'm trying to attach to.
