[libvirt] How to add uplink in esx virtual switch using libvirt
by varun bhatnagar 02 Sep '13

02 Sep '13

Hi, I have an ESXi server, on top of it I have created one VM whose IP address is 192.168.79.1. I want to connect to the VM on ESXi server from my host machine but I am not able to do it. I have created a network "networkforSC" and I have pasted my xml file content below but I am not able to add any uplink (how to add it?) . Below is the xml file of my node as well as the network which I am creating on my ESXi server *<domain type='vmware'>* *<name>testNode</name>* *<uuid>50115e16-9bdc-49d7-f171-53c4d7f91710</uuid>* *<memory>1048576</memory>* *<currentMemory>1048576</currentMemory>* *<vcpu>1</vcpu>* *<console>/dev/console</console>* *<os>* *<type arch='x86_64'>hvm</type>* *</os>* *<devices>* *<disk type='file' device='disk'>* *<source file='[datastore1] testNode/testNode.vmdk'/>* *<target dev='sda' bus='scsi'/>* *<address type='drive' controller='0' bus='0' unit='0'/>* *</disk>* *<controller type='scsi' index='0' model='lsilogic'/>* ** *<interface type='bridge'>* *<mac address='00:50:56:25:48:c7'/>* *<source bridge='VM Network'/>* *</interface>* *<interface type='bridge'>* *<source bridge='test'/>* *</interface>* *</devices>* *</domain>* ########################################## Network File: *<network>* *<name>networkforSC</name>* *<portgroup name='test'>* *</portgroup>* *</network>* I have checked the network which got created on the server. As I have not attached any uplink (vmnic0) I can not see it (I want to attach it). #esxcli network vswitch standard list * * *networkforSC* *Name: networkforSC* *Class: etherswitch* *Num Ports: 128* *Used Ports: 2* *Configured Ports: 128* *MTU: 1500* *CDP Status: listen* *Beacon Enabled: false* *Beacon Threshold: 3* *Beacon Required By:* *Uplinks:* *Portgroups: test* Can anyone please help me out in adding the uplink and also can anyone tell me whether I am going in a right direction so that I could ping my virtual machine created on ESXi server. Regards, Varun

[libvirt] [PATCH] Add forwarders attribute to <dns /> element.
by Diego Woitasen 02 Sep '13

02 Sep '13

Useful to set custom forwarders instead of using the contents of /etc/resolv.conf. It helps me to setup dnsmasq as local nameserver to resolv VM domain names from domain 0, when domain option is used.

[libvirt] [PATCHv2 0/2] Support setting the 'removable' flag for USB disks
by Fred A. Kemp 02 Sep '13

02 Sep '13

From: "Fred A. Kemp" <anonym(a)riseup.net> The commit message of patch #2 explains the purpose of this patch set. A review would be greatly appreciated! Note that I've only added the new capability for usb-storage.removable to the qemu help tests of qemu(-kvm) version 1.2.0, since that's what I had easily available to get the output of `-device usb-storage,?` from. I hope that's not an issue, otherwise, is there a way to obtain these outputs without having to hunt down and install all supported versions?

[libvirt] Release of libvirt-1.1.2
by Daniel Veillard 02 Sep '13

02 Sep '13

As scheduled I have pushed the tarballs and rpms of the new release at the usual place: ftp://libvirt.org/libvirt/ This is a medium sized release with less than 300 commits, with a inclination toward code improvements and bugs fixes, in particular fixes for 4 CVEs. It may be a good idea to upgrade ! Features: - various improvements to libxl driver (Jim Fehlig, Bamvor Jian Zhang) - systemd integration improvements (Daniel P. Berrange, Mooli Tayer) - Add flag to BaselineCPU API to return detailed CPU features (Don Dugger) - Introduce a virt-login-shell binary (Dan Walsh) - conf: add startupPolicy attribute for harddisk (Guannan Ren) Security: - provide supplemental groups even when parsing label (CVE-2013-4291) (Eric Blake) - Add bounds checking on virDomainMigrate*Params RPC calls (CVE-2013-4292) (Daniel P.

[libvirt] Entering freeze for libvirt-1.1.2
by Daniel Veillard 02 Sep '13

02 Sep '13

I am a day late but I finally tagged the release candidate 1 of 1.1.2 in git and push the tarball and rpms to the usual place: ftp://libvirt.org/libvirt/ so the plan is to have an rc2 candidate on friday and if everything looks good push the final release 1.1.2 on Monday. Please give it a try especially for potential portability issues, thanks in advance !

[libvirt] [PATCH] qemu_hotplug: Resolve DEADCODE coverity error
by John Ferlan 01 Sep '13

01 Sep '13

Remove unused 'cgroup' variable in qemuDomainAttachDeviceDiskLive() to resolve coverity DEADCODE complaint --- Refactoring of qemuDomainAttachDeviceDiskLive() in the following patch: https://www.redhat.com/archives/libvir-list/2013-August/msg00079.html seemed to wake up Coverity and it complained about deadcode as a result of 'cgroup' only ever been NULL thus the check for it to be non-NULL in order to call qemuTeardownDiskCgroup() would not be able to occur. The code actually hadn't changed, but for some reason coverity now found it. Followed example in qemuDomainChangeDiskMediaLive() and just removed the 'cgroup' variable. src/qemu/qemu_hotplug.c | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) diff --git a/src/qemu/qemu_hotplug.c b/src/qemu/qemu_hotplug.c index 9c655ff..6cdee44 100644 --- a/src/qemu/qemu_hotplug.c +++ b/src/qemu/qemu_hotplug.c @@ -683,7 +683,6 @@ qemuDomainAttachDeviceDiskLive(virConnectPtr conn, virDomainDiskDefPtr orig_disk = NULL; virDomainDeviceDefPtr dev_copy = NULL; virDomainDiskDefPtr tmp = NULL; - virCgroupPtr cgroup = NULL; virCapsPtr caps = NULL; int ret = -1; @@ -773,10 +772,10 @@ qemuDomainAttachDeviceDiskLive(virConnectPtr conn, break; } - if (ret != 0 && cgroup) { - if (qemuTeardownDiskCgroup(vm, disk) < 0) - VIR_WARN("Failed to teardown cgroup for disk path %s", - NULLSTR(disk->src)); + if (ret != 0 && + qemuTeardownDiskCgroup(vm, disk) < 0) { + VIR_WARN("Failed to teardown cgroup for disk path %s", + NULLSTR(disk->src)); } end: -- 1.8.3.1
