[libvirt] kvm networking () on debian unstable
by Thomas Koch 22 Sep '09

22 Sep '09

Hi, I'm trying to get NAT networking running as described in http://libvirt.org/formatnetwork.html#examplesNAT But in the guest, ifconfig shows only the lo interface. I created the kvm image (debian lenny 5.0.3) directly with qemu-img and kvm, because virt- install also didn't work. Afterwards I created the XML file for libvirt: <domain type='kvm'> <name>hadoop1</name> <uuid>c40b6644-362a-e5ab-8825-cd1a7fbe24eb</uuid> <memory>524288</memory> <currentMemory>524288</currentMemory> <vcpu>1</vcpu> <os> <type arch='x86_64' machine='pc'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='qcow2'/> <source file='/var/lib/libvirt/images/hadoop1.qcow2'/> <target dev='hda' bus='ide'/> </disk> <interface type='network'> <mac address='52:54:00:05:74:bb'/> <source network='default'/> <model type='virtio'/> </interface>  <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='de-ch'/> <video> <model type='cirrus' vram='9216' heads='1'/> </video> </devices> </domain> The network config is: <network> <name>default</name> <bridge name="virbr0" /> <forward/> <ip address="192.168.122.1" netmask="255.255.255.0"> <dhcp> <range start="192.168.122.2" end="192.168.122.254" /> </dhcp> </ip> </network> ifconfig of the host (needs cleanup, I know): eth1 Link encap:Ethernet Hardware Adresse 00:1c:25:18:4d:e6 UP BROADCAST RUNNING MULTICAST MTU:1500 Metrik:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 Kollisionen:0 Sendewarteschlangenlänge:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Speicher:fe200000-fe220000 eth1:avahi Link encap:Ethernet Hardware Adresse 00:1c:25:18:4d:e6 inet Adresse:169.254.6.97 Bcast:169.254.255.255 Maske:255.255.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metrik:1 Speicher:fe200000-fe220000 lo Link encap:Lokale Schleife inet Adresse:127.0.0.1 Maske:255.0.0.0 inet6-Adresse: ::1/128 Gültigkeitsbereich:Maschine UP LOOPBACK RUNNING MTU:16436 Metrik:1 RX packets:160751 errors:0 dropped:0 overruns:0 frame:0 TX packets:160751 errors:0 dropped:0 overruns:0 carrier:0 Kollisionen:0 Sendewarteschlangenlänge:0 RX bytes:27262569 (25.9 MiB) TX bytes:27262569 (25.9 MiB) virbr0 Link encap:Ethernet Hardware Adresse 4a:30:15:4d:b5:0d inet Adresse:192.168.122.1 Bcast:192.168.122.255 Maske:255.255.255.0 inet6-Adresse: fe80::8804:ecff:febc:fa54/64 Gültigkeitsbereich:Verbindung UP BROADCAST RUNNING MULTICAST MTU:1500 Metrik:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:299 errors:0 dropped:0 overruns:0 carrier:0 Kollisionen:0 Sendewarteschlangenlänge:0 RX bytes:0 (0.0 B) TX bytes:47842 (46.7 KiB) vnet0 Link encap:Ethernet Hardware Adresse 4a:30:15:4d:b5:0d inet6-Adresse: fe80::4830:15ff:fe4d:b50d/64 Gültigkeitsbereich:Verbindung UP BROADCAST RUNNING MULTICAST MTU:1500 Metrik:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:128 errors:0 dropped:0 overruns:0 carrier:0 Kollisionen:0 Sendewarteschlangenlänge:500 RX bytes:0 (0.0 B) TX bytes:16426 (16.0 KiB) wlan0 Link encap:Ethernet Hardware Adresse 00:1d:e0:08:89:21 inet Adresse:192.168.178.23 Bcast:192.168.178.255 Maske:255.255.255.0 inet6-Adresse: fe80::21d:e0ff:fe08:8921/64 Gültigkeitsbereich:Verbindung UP BROADCAST RUNNING MULTICAST MTU:1500 Metrik:1 RX packets:10608 errors:0 dropped:0 overruns:0 frame:0 TX packets:10358 errors:0 dropped:0 overruns:0 carrier:0 Kollisionen:0 Sendewarteschlangenlänge:1000 RX bytes:7515487 (7.1 MiB) TX bytes:1367200 (1.3 MiB) wmaster0 Link encap:UNSPEC Hardware Adresse 00-1D- E0-08-89-21-00-00-00-00-00-00-00-00-00-00 UP BROADCAST RUNNING MULTICAST MTU:1500 Metrik:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 Kollisionen:0 Sendewarteschlangenlänge:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Thanks for any help, Thomas Koch, http://www.koch.ro

Hello The title says it all. Here's some doc explaining the new syntax of the video and graphic elements in the domain XML. It (probably) won't get me any literary awards but, eh, it's a start :) Florian

[libvirt] [PATCH: 0/MANY] Re-arrange files in the source tree
by Daniel P. Berrange 22 Sep '09

22 Sep '09

This is a followup to http://www.redhat.com/archives/libvir-list/2009-September/msg00477.html I am not actually going to spam the list with all the patches, since it'd generate a HUGE series of mails. Instead I have published a branch containing all the patches which you can directly pull into your GIT checkout. I recommend you do the following set of steps. - make maintainer-clean - git checkout master - git pull - git remote add -f danb git://gitorious.org/~berrange/libvirt/staging.git - git checkout -b rearrange danb/rearrange You will now have a checkout on a branch called 'rearrange' containing all my patches applied. If you want to go straight into building it, the normal build process still applies eg ./autogen && make I've committed the changes in a large series of steps to make it easier to see what's going on at each point. To see the list of changes run the following git log -b berrange/rearrange master.. The changes basically follow everything we discussed in the previous thread I've added a src/README file which describes the split of sub-directories. I'll reproduce the content here for convenience libvirt library code README =========================== The directory provides the bulk of the libvirt codebase. Everything except for the libvirtd daemon and client tools. The build uses a large number of libtool convenience libraries - one for each child directory, and then links them together for the final libvirt.so, although some bits get linked directly to libvirtd daemon instead. The files directly in this directory are supporting the public API entry points & data structures. There are two core shared modules to be aware of: * util/ - a collection of shared APIs that can be used by any code. This directory is always in the include path for all things built * conf/ - APIs for parsing / manipulating all the official XML files used by the public API. This directory is only in the include path for driver implementation modules Then there are the hypervisor implementations: * esx/ - VMWare ESX and GSX support using XMLRPC * lxc/ - Linux Native Containers * opennebula/ - Open Nebula using XMLRPC * openvz/ - OpenVZ containers using cli tools * phyp/ - IBM Power Hypervisor using CLI tools over SSH * qemu/ - QEMU / KVM using qemu CLI/monitor * remote/ - Generic libvirt native RPC client * test/ - A "mock" driver for testing * uml/ - User Mode Linux * vbox/ - Virtual Box using native API * xen/ - Xen using hypercalls, XenD SEXPR & XenStore Finally some secondary drivers that are shared for several HVs. Currently these are used by LXC, OpenVZ, QEMU, UML and Xen drivers. The ESX, OpenNebula, Power Hypervisor, Remote, Test & VirtualBox drivers all implement the secondary drivers directly * interface/ - Host network interface management * network/ - Virtual NAT networking * node_device/ - Host device enumeration * secret/ - Secret management * security/ - Mandatory access control drivers * storage/ - Storage management drivers Since both the hypervisor and secondary drivers can be built as dlopen()able modules, it is *FORBIDDEN* to have build dependancies between these directories. Drivers are only allowed to depend on the public API, and the internal APIs in the util/ and conf/ directories For the docs directory, I left the docs/libvirt-{api,refs}.xml files in GIT as Daniel requested. I have removed the *.html, devhelp/*.html and html/*.html files though. These are all re-generated when doing make in the docs directory, and the generated HTML is included in the tar.gz when doing make dist. So end users won't have to rebuild them, only libvirt developers The example programs & XML is now all under examples/ with various sub-directories. The qemud/ directory is renamed to daemon/ The python/ directory has its file nameing changed and the genrator tweaked so that its more obvious which are generated files and which are manually written. virsh has moved to the tools/ directory, and the docs/pki_check.sh file has been turned into a real installed tool, tools/virt-pki-validate along with man page. A few minor bugs were fixed along the way (eg bogus include files discovered when files were moved) & unused png/gif images in docs/ There should be no FUNCTIONAL change in any of this work though. It is a pure re-arrangement of files. Please try out a build using this 'rearrange' branch from gitorious. Since this is a huge change I'd like to apply this to the master repo as soon as people can verify its doing the right thing for them. FWIW, I checked an RPM build and 'make distcheck' too with no issues.

[libvirt] [PATCH] lxc: suspend/resume support
by Ryota Ozaki 22 Sep '09

22 Sep '09

Hi, This patch implements suspend/resume functions for LXC using cgroups freezer subsystem. The use of freezer is quite simple and well documented in Documentation/cgroups/freezer-subsystem.txt. The patch just uses it as it is. That is like: # freeze the container echo FROZEN > /target/container/freezer.state # unfreeze the container echo THAWED > /target/container/freezer.state However, freezer sometimes looks behaving different from the document. The document is saying "It's important to note that freezing can be incomplete. In that case we return EBUSY.", but in the case returning 0, freezing can be incomplete under load. So the code doesn't believe the return value and always check the content of freezer.state to identify whether the freezing is finished. Please refer to the comments in the code for more details. And the patch modifies domain_conf.c that assumes obj->monitor_chr != NULL but that is true only when qemu.

[libvirt] [PATCH] Power Hypervisor now with libssh2
by Eduardo Otubo 21 Sep '09

21 Sep '09

Hello friends, This is the new version of phyp driver now using libssh2. I also did some other changes: * Added some debug information. Sometimes its worth to know which command is being executed and where. So I added the PHYP_CMD_DEBUG macro. * All the connection startup is now "hard coded" in libssh2. For example, I need to open the socket and start the connection all by myself. Not a big deal, but in a near future I am planning to send a patch to libssh2 to encapsulate all these procedures into functions, hence, less code, probably less bugs :) * There is a lot of "out of scope" functions in the bottom of the file. In the next patch I may put all those together in a phyp_config.[ch] in order to get things clearer. What's up next: * The problem of handling the UUID in a centralized way still remains. I started to handle this by opening a sftp connection to the HMC system and transfer my UUID database. But there is an odd behavior that makes the driver connect OR NOT to some HMC systems. * CPU management: this feature planned to be released in this version is not ready yet due to the issue above. * Storage management. Vacations: I'll be on vacations from 26th/august to 14th/september. I'll check my emails in the meanwhile, but no so often. Anyway, any comments on this patch are always welcome :) []'s -- Eduardo Otubo Software Engineer Linux Technology Center IBM Systems & Technology Group Mobile: +55 19 8135 0885 otubo(a)linux.vnet.ibm.com

[libvirt] virsh migrate with libvirt-0.6.2: failed to start listening VM
by David Wilcox 21 Sep '09

21 Sep '09

Hello, I'm trying to migrate a vm from a fedora 11 host to another fedora 11 host. Both hosts are on the same subnet. Both machines have identical architectures. We use an nfs shared storage mounted, but both machines also have their own hard drives. I get the machines up and running alright. Here's the printout of virsh when I try to do the migration. # virsh list Id Name State ---------------------------------- 1 windowsxp running 2 potato running # virsh migrate 1 qemu+ssh://prodigy/system Password: error: operation failed: failed to start listening VM On the other machine, the log file that gets created under /var/log/libvirt/qemo/windowsxp.log LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin /usr/bin/qemu-kvm -S -M pc -m 512 -smp 1 -name windowsxp -uuid 24d2fd62-ed4f-a321-e264-200b347cfa6c -monitor pty -pidfile /var/run/libvirt/qemu//windowsxp.pid -localtime -no-acpi -boot c -drive file=/var/lib/libvirt/images/windowsxp.img,if=ide,index=0,boot=on -drive file=/aml/iso/windows_xp_sp3.iso,if=ide,media=cdrom,index=2 -net nic,macaddr=54:52:00:01:f1:06,vlan=0 -net tap,fd=19,vlan=0 -serial pty -parallel none -usb -usbdevice tablet -vnc 127.0.0.1:0 -soundhw es1370 -incoming tcp:0.0.0.0:49159 qemu: could not open disk image /var/lib/libvirt/images/windowsxp.img I would think that the virtual machine should copy from the one machine to the other. Isn't libvirt supposed to copy the image file? What's even stranger, I've been trying this for awhile. It's failed every time, except once when it succeded. I don't know what made it succeed in that case and fail in all the other cases. Thanks.

[libvirt] regarding the network information for Domain
by anuj rampal 18 Sep '09

Hi all, im trying to call libvirt api from windows. I have created a guest OS(windows) using the libvirt api from my windows machine. It gets created fine it also gets the the IP address from the DHCP also. So all works fine. Now to RDP into the machine what I have to do is 1. logon to my host machine. 2. open the guest OS using either "virt-viewer" or "virt-manager". 3. check out the IP address of the machine. 4. then RDP into the guest OS. My Question: Is there a way to find The IP address of the Guest OS.??? ---------------------------------------------------------------------------------------------------------------------------- im also trying to cross compile "virt-viewer 0.0.3" but this is what i get when i do make: [root@FC-11 virt-viewer-0.0.3]# make make all-recursive make[1]: Entering directory `/root/virt-viewer-0.0.3'

[libvirt] guests and pulseaudio fighting over audio devices
by Dave Allan 17 Sep '09

17 Sep '09

I noticed that when a KVM guest created with virt-manager is running on F10, sound on the physical host stops working. When all VMs are shutdown, sound starts working again. Removing the <sound> tag from the VM XML allows sound to work while the VM is booted. To further complicate troubleshooting, if audio is already playing when the guest is started it keeps playing, since pulse already has the device open. The message in /var/log/messages when I try to play audio is: pulseaudio[6492]: module-alsa-sink.c: Error opening PCM device front:0: Device or resource busy strace of pulseaudio shows: open("/dev/snd/pcmC0D0p", O_RDWR|O_NONBLOCK) = -1 EBUSY (Device or resource busy) but fuser and lsof show nothing. A trivial test program also sees Device or resource busy when trying to open /dev/snd/pcmC0D0p I am in favor of removing the <sound> tag from the default configuration, since I don't use sound from within guests and I do use sound on my desktop, but perhaps this behavior is specific to my configuration. I haven't investigated it exhaustively. What does everybody else think? Dave

[libvirt] Passing -no-kvm-irqchip to KVM/QEMU guests
by Garry Dolley 16 Sep '09

16 Sep '09

Dear libvirt, Is there a way to tell a KVM/QEMU guest managed by libvirt to start with the "-no-kvm-irqchip" argument? I have some FreeBSD 7 guests with timing issues, and if I try to start the VMs manually with -no-kvm-irqchip, the timing issues go away (the only known workaround right now). However, if the guest is managed by libvirt, I have found no way to pass this command line option. I'm running libvirt 0.6.4 on Ubuntu 9.04 Thoughts? -- Garry Dolley ARP Networks, Inc. | http://www.arpnetworks.com | (818) 206-0181 Data center, VPS, and IP Transit solutions Member Los Angeles County REACT, Unit 336 | WQGK336 Blog http://scie.nti.st

[libvirt] Python binding to virConnectListInterfaces
by Shahar Klein 16 Sep '09

16 Sep '09

Hi I'm trying to implement virConnectListInterfaces for the ESX driver (actually the esx_interface driver) but the python generator does not write the code for this function in generator.py this function is in a special table called: skip_impl and there is a comment saying: # Class methods which are written by hand in libvir.c but the Python-level # code is still automatically generated (so they are not in skip_function()) I'm not sure what does it mean should I implement in libvir.c? and I'm done? thanks ahead Shahar

[libvirt] [PATCH] doc: don't emit trailing blanks into generated and VC'd NEWS file
by Jim Meyering 15 Sep '09

Daniel Veillard reported that the generated and VC'd NEWS file was causing trouble because the latest version contains trailing spaces, which conflicts with our server-side hook to prevent that. Here's the fix to avoid emitting those trailing spaces: >From 8110d304f49a217021371321ade0026ccd2627e1 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Tue, 15 Sep 2009 15:01:26 +0200 Subject: [PATCH] doc: don't emit trailing blanks into generated and VC'd NEWS file * docs/Makefile.am ($(top_builddir)/NEWS): Filter out trailing white space. --- docs/Makefile.am | 1 + 1 files changed, 1 insertions(+), 0 deletions(-) diff --git a/docs/Makefile.am b/docs/Makefile.am index 9ac2f6d..1125931 100644 --- a/docs/Makefile.am +++ b/docs/Makefile.am @@ -131,6 +131,7 @@ $(top_builddir)/NEWS: $(top_srcdir)/docs/news.xsl $(top_srcdir)/docs/news.html.i $(XSLTPROC) --nonet $(top_srcdir)/docs/news.xsl \ $(top_srcdir)/docs/news.html.in \ | perl -0777 -pe 's/\n\n+$$/\n/' \ + | perl -pe 's/[ \t]+$//' \ > $@-t && mv $@-t $@ ; fi ); clean-local: -- 1.6.5.rc1.171.g3f463

[libvirt] Trouble booting Xen VM with NFS root file system
by Matthias Schmidt 15 Sep '09

15 Sep '09

Hi, I'm currently trying to boot a Xen VM with the root file system on NFS via libvirt. Previously we used a small python script and "xm create" to boot a number of VMs (which worked fine). Now I'm trying to integrate that functionality in a python project which uses libvirt, but sadly booting the VMs fail. The small script constructs a Xen command line which looks like the following: create =("/usr/sbin/xm create /foo.cfg \ kernel=%s ramdisk=%s memory=64\ root=/dev/nfs nfs_server=%s nfs_root=%s name=%s vif='mac=%s'\ dhcp='dhcp' vcpus=1 extra='init=/stateless.sh xencons=tty1'\ ")%(vm_kernel, vm_ramdisk, vm_nfs_server, vm_nfs_root, hostname, vif) kernel and ramdisk are the path to the installed version, vm_nfs_server is the IP address of the NFS server and vm_nfs_root the path to the operating system installation (which is a Debian Linux). Firing up the script brings up all VMs with a read-only NFS root file system. Now I tried to do this with libvirt, but all attempts failed with the following error popping up after the VM boots (after a certain time(out)): Gave up waiting for root device. Common problems: - Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Check root= (did the system wait for the right device?) - Missing modules (cat /proc/modules; ls /dev) ALERT! /dev/nfs does not exist. Dropping to a shell! BusyBox v1.10.2 (Debian 1:1.10.2-2) built-in shell (ash) Enter 'help' for a list of built-in commands. /bin/sh: can't access tty; job control turned off (initramfs) cat /proc/cmdline root=/dev/nfs nfs_server=10.0.0.150 nfs_root=/opt/xge/util/ph vif="mac=1A:00:00:00:00:64" dhcp=dhcp extra="init=./stateless.sh xencons=tty" The cmdline looks the same as in the script, but booting won't work. I can provide the libvirt XML used to boot the VM and further information if that is necessary. Cheers Matthias PS: I'm using Xen 3.2.1, Kernel 2.6.26 and libvirt 0.6.3 from Debian here.

[libvirt] RFE storage cloning across connections.
by "Jóhann B. Guðmundsson" 15 Sep '09

Virt-manager now supports migration and VM cloning however cloning only works within a connection though so you can't clone to another machine. It certainly would be a nice addition if supports storage cloning across connections. Best regards. Jóhann B.
