[libvirt] [PATCH] events: Don't fail on registering events for two different domains
by Michal Privoznik 27 Jun '12

27 Jun '12

virConnectDomainEventRegisterAny() takes a domain as an argument. So it should be possible to register the same event (be it VIR_DOMAIN_EVENT_ID_LIFECYCLE for example) for two different domains. That is, we need to take domain into account when searching for duplicate event being already registered. --- src/conf/domain_event.c | 6 +++++- 1 files changed, 5 insertions(+), 1 deletions(-) diff --git a/src/conf/domain_event.c b/src/conf/domain_event.c index 4ecc413..3cfd940 100644 --- a/src/conf/domain_event.c +++ b/src/conf/domain_event.c @@ -363,7 +363,11 @@ virDomainEventCallbackListAddID(virConnectPtr conn, for (i = 0 ; i < cbList->count ; i++) { if (cbList->callbacks[i]->cb == VIR_DOMAIN_EVENT_CALLBACK(callback) && cbList->callbacks[i]->eventID == eventID && - cbList->callbacks[i]->conn == conn) { + cbList->callbacks[i]->conn == conn && + ((dom && cbList->callbacks[i]->dom && + memcmp(cbList->callbacks[i]->dom->uuid, + dom->uuid, VIR_UUID_BUFLEN) == 0) || + (!dom && !cbList->callbacks[i]->dom))) { eventReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("event callback already tracked")); return -1; -- 1.7.3.4

[libvirt] [PATCH] virsh: Add domdisplay command for VNC and SPICE
by Doug Goldstein 27 Jun '12

27 Jun '12

Add a new 'domdisplay' command that provides a URI for both VNC and SPICE connections. Presently the 'vncdisplay' command provides you with the port info that QEMU is listening on but there is no counterpart for SPICE. Additionally this provides you with the bind address as specified in the XML, which the existing 'vncdisplay' lacks.

[libvirt] Accessing VM by only specigied users.
by Pankaj Rawat 27 Jun '12

27 Jun '12

Hi All, I want to access vm via noon-root user. To explain my scenario : Suppose I have following VM VM1,VM2,VM3,VM4 I want User1 access VM1 only User2 access VM2 only User3 access VM3 only User4 access VM4 only By access I mean that he should be able to start and console on Vm. Moreover only he can list the vm by Virsh list command Is that possible, like in VMware?

[libvirt] qemu -net_user features
by Chet Maghz 27 Jun '12

27 Jun '12

Hi, I am trying to specify the host name, dns address and some other features provided by qemu -net_user. Right now Im adding a new name space at the end of my xml, like the one below: <qemu:commandline> <qemu:arg value='-net'/> <qemu:arg value='user,hostname=blahblah'/> </qemu:commandline> I am wondering if it is possible to set them within the <interface> name space. My concern is I need to set the host name and dns address using SLiRP for other hypervisors (such as XeN) and it seems they only accept standard libvirt xml tags. Would appreciate if you could give a response on this, and a reason if such thing is not possible. Thanks in advance. Chet

[libvirt] KVM/QEMU -net_user host and dns addr
by Chet Maghz 27 Jun '12

27 Jun '12

Hi, I am using libvirt with kvm/qemu. And Im using -net_user network option of kvm/qemu. In order to send the dns addr and host addr I have to modify the xml by my slef. I am wondering why there is no built in function in libvirt api to access/modify dns addr and host addr from within libvirt under user mode network of kvm/qemu (-net_user). Is there a reason for not having this feature or is it just not been implemented? Chet

[libvirt] pci bus slot in libvirt
by Fong Vang 27 Jun '12

27 Jun '12

What's the best way to configure multiple disks in libvirt? How many slots can you have? This is from the xml dump: In some of my configurations, I have this: <disk type='block' device='disk'> <driver name='qemu' type='raw' cache='none' io='native'/> <source dev='/dev/sdb1'/> <target dev='vdb' bus='virtio'/> <alias name='virtio-disk1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </disk> while others are created as such: <devices> <emulator>/usr/bin/qemu-kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/data2/VMs/libvirt/images/win2k8-1.qcow2'/> <target dev='hda' bus='ide'/> <alias name='ide0-0-0'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> Which way is better? The top one defines the bus and slot while the bottom defines the controller, bus, target, and unit. BTW, how many slots can we define per bus?

[libvirt] [PATCHv2 0/5] Basic Enablement of s390

Resending as a thread, same content. Please ignore previous submission. The first series of patches aimed to enable libvirt to manage qemu/kvm domains hosted on the System z platform. The patches in this series address s390 specifics of node and hypervisor. Patches 2,3 and 5 are written by Thang Pham <thang.pham(a)us.ibm.com> the others are my doing. Since they all should go together, I am sending in Thang's as well, hoping to facilitate the review a bit this way.
