[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] Libvirt on Ohloh
by Guido Günther 27 Jun '12

27 Jun '12

Hi, I just noticed that ohloh tracks both libvirt-glib and libvirt under libvirt: https://www.ohloh.net/p/libvirt/enlistments Any objections to removing libvirt-glib from there (it's a separate project on ohloh as well). Cheers, -- Guido

[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
by Viktor Mihajlovski 27 Jun '12

27 Jun '12

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. Thang Pham (3): S390: CPU support for s390(x) S390: Fixed Parser for /proc/cpuinfo needs to be adapted for your architecture S390: Added sysinfo for host on s390x. Viktor Mihajlovski (2): S390: Override QEMU_CAPS_NO_ACPI for s390x S390: Fixed core identification for s390 src/Makefile.am | 1 + src/cpu/cpu.c | 2 + src/cpu/cpu_s390x.c | 80 ++++++++++++++++++++++ src/cpu/cpu_s390x.h | 31 +++++++++ src/nodeinfo.c | 11 +++ src/qemu/qemu_capabilities.c | 5 ++ src/util/sysinfo.c | 154 ++++++++++++++++++++++++++++++++++++++++++ 7 files changed, 284 insertions(+), 0 deletions(-) create mode 100644 src/cpu/cpu_s390x.c create mode 100644 src/cpu/cpu_s390x.h

Hi, in order to bring libvirt-java closer to head i will start send a few patches therefore. I start with the domain flags and error constants, as these dont break any older clients, but make it possible to get usefull errorcodes when using it with recent libvirt. Greetings Stefan Majer (2): Added error constants up to libvirt-0.9.12 Added domain flags up to libvirt-0.9.12 src/main/java/org/libvirt/Domain.java | 38 +++++++++++++++++++++++++--- src/main/java/org/libvirt/Error.java | 45 +++++++++++++++++++++++++++++---- 2 files changed, 74 insertions(+), 9 deletions(-) -- 1.7.9.5 -- Stefan Majer
