[libvirt] [PATCH V2] Expose all CPU features in host definition

by Don Dugger

[V2 - Improve the error handling] I've opened BZ 697141 on this as I would consider it more a bug than a feature request. Anyway, to re-iterate my rationale from the BZ: The virConnectGetCapabilities API describes the host capabilities by returning an XML description that includes the CPU model name and a set of CPU features. The problem is that any features that are part of the CPU model are not explicitly listed, they are assumed to be part of the definition of that CPU model. This makes it extremely difficult for the caller of this API to check for the presence of a specific CPU feature, the caller would have to know what features are part of which CPU models, a very daunting task. This patch solves this problem by having the API return a model name, as it currently does, but it will also explicitly list all of the CPU features that are present. This would make it much easier for a caller of this API to check for specific features.

[libvirt] [PATCH] lxc: Create /dev/tty within a container

by Richard Weinberger

Many applications use /dev/tty to read from stdin. E.g. zypper on openSUSE. Let's create this device node to unbreak those applications.

[libvirt] RFC: Introduce API to query IP addresses for given domain

by Nehal J. Wani

Hello, fellow developers! I am a GSoC candidate this year working for libvirt.org. My project is "Introduce API to query IP addresses for given domain". The discussion regarding this feature had started here: http://www.mail-archive.com/libvir-list@redhat.com/msg51857.html and then Michal had sent a patch too (refer: http://www.mail-archive.com/libvir-list@redhat.com/msg57141.html). But it was not pushed upstream due to lack of extensibility. So far I've come up with an API and I want to get your opinion before I start writing the rest so I don't follow the wrong direction. Following are the valid commands: domifaddr <domain-name> domifaddr <domain-name> <interface-name> domifaddr <domain-name> <interface-name> <method> domifaddr <domain-name> <method> methods: (i) Querying qemu-guest-agent (ii) Getting info from dnsmasq.leases file (iii) Using the nwfilter to snoop the traffic If no method is mentioned, qemu-guest-agent will be used. Previous attempts by Michal had used structs and xml. Structs bring in restrictions and xml has to be parsed. Hence I am not planning to continue with either of these. As a start, I would like to know your comments about my API which queries the qemu-guest-agent and returns the results in virTypedParameter **params. Format(JSON) in which the qemu guest agent returns info: [{"name":"lo", "ip-addresses": [{"ip-address-type":"ipv4","ip-address":"127.0.0.1","prefix":8}, {"ip-address-type":"ipv6","ip-address":"::1","prefix":128}], "hardware-address":"00:00:00:00:00:00"}, {"name":"eth0", "ip-addresses": [{"ip-address-type":"ipv4","ip-address":"192.168.122.42","prefix":24}, {"ip-address-type":"ipv6","ip-address":"fe80::5054:ff:fe09:d240","prefix":64}], "hardware-address":"52:54:00:09:d2:40"}] //Possible 1-D Structure (A little hassle to maintain) params[0] = {"iface-count",int,2} params[1] = {"iface-name",string,"lo"} params[2] = {"iface-hwaddr",string,"00:00:00:00:00:00"} params[3] = {"iface-addr-count",int,2} params[4] = {"iface-addr-type",string,"ipv4"} params[5] = {"iface-addr",string,"127.0.0.1"} params[6] = {"iface-addr-prefix",int,8} params[7] = {"iface-addr-type",string,"ipv6"} params[8] = {"iface-addr",string,"::1"} params[9] = {"iface-addr-prefix",int,128} .... .... .... //2D Structure: (Not very hasslefree, but easier to maintain as one interface per row) params[0] = {"iface-name",string,"lo"}{"iface-hwaddr",string,"00:00:00:00:00:00"}{"iface-addr-type",string,"ipv4"}{"iface-addr",string,"127.0.0.1"}{"iface-addr-prefix",int,8}{"iface-addr-type",string,"ipv6"}{"iface-addr",string,"::1"}{"iface-addr-prefix",int,128} params[1] = {"iface-name",string,"eth0"}{"iface-hwaddr",string,"52:54:00:09:d2:40"}{"iface-addr-type",string,"ipv4"}{"iface-addr",string,"192.168.122.42"}{"iface-addr-prefix",int,8}{"iface-addr-type",string,"ipv6"}{"iface-addr",string,"fe80::5054:ff:fe09:d240"}{"iface-addr-prefix",int,64} Function definitions that I intend to use are: static int remoteDispatchDomainInterfacesAddresses( virNetServerPtr server ATTRIBUTE_UNUSED, virNetServerClientPtr client, virNetMessagePtr msg ATTRIBUTE_UNUSED, virNetMessageErrorPtr rerr, remote_domain_interfaces_addresses_args *args, remote_domain_interfaces_addresses_ret *ret) int virDomainInterfacesAddresses (virDomainPtr dom, virTypedParameterPtr *params, int *nparams, unsigned int flags); typedef int (*virDrvDomainInterfacesAddresses) (virDomainPtr dom, virTypedParameterPtr *params, int *nparams, unsigned int flags); int virDomainInterfacesAddresses (virDomainPtr dom, virTypedParameterPtr *params, int *nparams, unsigned int flags) int qemuAgentGetInterfaces(qemuAgentPtr mon, virTypedParameterPtr *params, int *nparams) int qemuAgentGetInterfaces(qemuAgentPtr mon, virTypedParameterPtr *params, int *nparams); static int qemuDomainInterfacesAddresses(virDomainPtr dom, virTypedParameterPtr *params, int *nparams, unsigned int flags) static int remoteDomainInterfacesAddresses(virDomainPtr dom, virTypedParameterPtr *params, int *nparams, unsigned int flags) static bool cmdDomIfAddr(vshControl *ctl, const vshCmd *cmd) Also, It will be helpful to know whether we want the client to first query for the number of parameters and then send the request or have the server side allocate appropriate memory and return the result once in for all. In the latter case, I'll be using something of the kind virTypedParameterPtr ***params. Thanking You, Nehal J. Wani UG2, BTech CS+MS(CL) IIIT-Hyderabad http://commanlinewani.blogspot.com

We need to set memory limits in several cases: - when setting hard_limit in memory cgroup - when starting a domain with a VFIO PCI device attached - when hotplugging a VFIO PCI device - when memoryBacking/locked is used This series makes use of a shared code to compute the limits in all of those cases.

[libvirt] [PATCH glib] Fix name of gvir_config_domain_chardev_source_pty_set_path

by Daniel P. Berrange

From: "Daniel P. Berrange" <berrange(a)redhat.com> The method gvir_config_domain_chardev_source_pty_set_path was accidentally called gvir_config_domain_source_pty_set_path.

[libvirt] virsh live migration w/o shared storage fails with error as vm is not running

by chandrashekar shastri

Hi All, We are testing the upstream KVM with : Kernel, Qemu, Libvirt, Virt-Manager is built from the source (git). kernel version : 3.9.0+ qemu version : QEMU emulator version 1.5.0 libvirt version : 1.0.5 virt-install : 0.600.3 I have followed the below steps to test the "Live migration w/o shared storage" feature : 1. Created the qemu-img create -f qcow2 vm.qcow2 12G on the destination host which is same as the source. 2. Started the guest on the source 3. Started the vncdisplay to monitor the guest 4. Initiated the migration "virsh migrate --live rhel64-64 qemu+ssh://9.126.89.202/system --verbose --copy-storage-all" 5. It started the copying the storage from souce to destination (conitinously monitored it was growing) 6. Guest on the destination was paused and was running on the source 7. At some point the VM on the source shutdown and got an error on the vnc display as " Viewport: write: Broken pipe (32)" and the VM on the destination was undefined. Below is the libvirt debug log, please let me with your comments.

[libvirt] [PATCH 0/4] libxl: implement some chuncks of the NUMA interface

by Dario Faggioli

Hi Jim, Everyone, First patch series, so maybe a small introduction is required: I'm Dario and I work for Citrix on improving the NUMA support of Xen. This patch series implements some of the missing bits and pieces, in the libxl driver, regarding obtaining per-host and per-domain NUMA related information. It's not the full libvirt NUMA interface, since we don't have all we would need for that in Xen yet (we will in the next version, 4.4), but it's certainly better than having nothing! :-) Basically, I'm enhancing capability reporting, to cover NUMA topology (patch 01), and I'm implementing nodeGetCellsFreeMemory (patch 02) and virDomainGetNumaParameters (patch 04) for the libxl driver. This last one requires at least Xen 4.3, so I put the implementation within the proper #ifdef-ery. What I'm really not sure about is patch 03, which is something I need if I want patch 04 to function properly. Basically it is about advertising that the libxl driver supports VIR_TYPED_PARAM_STRING. I looked at how that is done in the qemu driver, but I'm not entirely sure I completely understood the logic behind it, so, please, tell me if I missed or misinterpreted anything! In particular, should I have added more of those "flags &= ~VIR_TYPED_PARAM_STRING_OKAY;" statements, as it happens in the qemu driver? If yes, in which functions? Finally, allow me to say that it was a while that I wanted start hacking a bit on libvirt. I'm really glad I've eventually been able to do so, and I definitely plan to continue (with particular focus on NUMA related stuff). Comments are of course more than welcome. :-) Thanks and Regards, Dario --- Dario Faggioli (4): libxl: implement NUMA capabilities reporting libxl: implement per NUMA node free memory reporting libxl: advertise the support for VIR_TYPED_PARAM_STRING libxl: implement virDomainGetNumaParameters src/libxl/libxl_conf.c | 128 +++++++++++++++++++++++++++++- src/libxl/libxl_driver.c | 199 ++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 326 insertions(+), 1 deletion(-) -- <<This happens because I choose it to happen!>> (Raistlin Majere) ----------------------------------------------------------------- Dario Faggioli, Ph.D, http://about.me/dario.faggioli Senior Software Engineer, Citrix Systems R&D Ltd., Cambridge (UK)
