[libvirt] Refactor libvirt spec file
by Daniel P. Berrange 28 Sep '09

28 Sep '09

The following patch refactors the libvirt spec file conditional logic to make it a little easier to manage all the different Fedora/RHEL OS build variations, and also allow for easy creation of a client-only build The patch follows, but I'm including the full specfile below too, since its easier to understand than the diff # -*- rpm-spec -*- # A client only build will create a libvirt.so only containing # the generic RPC driver, and test driver and no libvirtd # Default to a full server + client build %define client_only 0 # Now turn off server build in certain cases # RHEL-5 builds are client-only for s390, ppc %if 0%{?rhel} == 5 %ifnarch i386 i586 i686 x86_64 ia64 %define client_only 1 %endif %endif # Disable all server side drivers if client only build requested %if %{client_only} %define server_drivers 0 %else %define server_drivers 1 %endif # Now set the defaults for all the important features, independant # of any particular OS # First the daemon itself %define with_libvirtd 0%{!?_without_libvirtd:%{server_drivers}} %define with_avahi 0%{!?_without_avahi:%{server_drivers}} # Then the hypervisor drivers %define with_xen 0%{!?_without_xen:%{server_drivers}} %define with_xen_proxy 0%{!?_without_xen_proxy:%{server_drivers}} %define with_qemu 0%{!?_without_qemu:%{server_drivers}} %define with_openvz 0%{!?_without_openvz:%{server_drivers}} %define with_lxc 0%{!?_without_lxc:%{server_drivers}} %define with_vbox 0%{!?_without_vbox:%{server_drivers}} %define with_uml 0%{!?_without_uml:%{server_drivers}} %define with_one 0%{!?_without_one:%{server_drivers}} %define with_phyp 0%{!?_without_phyp:%{server_drivers}} %define with_esx 0%{!?_without_esx:%{server_drivers}} # Then the secondary host drivers %define with_network 0%{!?_without_network:%{server_drivers}} %define with_storage_fs 0%{!?_without_storage_fs:%{server_drivers}} %define with_storage_lvm 0%{!?_without_storage_lvm:%{server_drivers}} %define with_storage_iscsi 0%{!?_without_storage_iscsi:%{server_drivers}} %define with_storage_disk 0%{!?_without_storage_disk:%{server_drivers}} %define with_storage_mpath 0%{!?_without_storage_mpath:%{server_drivers}} %define with_numactl 0%{!?_without_numactl:%{server_drivers}} %define with_selinux 0%{!?_without_selinux:%{server_drivers}} %define with_hal 0%{!?_without_hal:%{server_drivers}} # A few optional bits off by default, we enable later %define with_polkit 0%{!?_without_polkit:0} %define with_capng 0%{!?_without_capng:0} %define with_netcf 0%{!?_without_netcf:0} # Non-server/HV driver defaults which are always enabled %define with_python 0%{!?_without_python:1} %define with_sasl 0%{!?_without_sasl:1} # Finally set the OS / architecture specific special cases # Xen is available only on i386 x86_64 ia64 %ifnarch i386 i586 i686 x86_64 ia64 %define with_xen 0 %endif # RHEL doesn't ship OpenVZ, VBox, UML, OpenNebula, PowerHypervisor or ESX %if 0%{?rhel} %define with_openvz 0 %define with_vbox 0 %define with_uml 0 %define with_one 0 %define with_phyp 0 %define with_esx 0 %endif # RHEL-5 has restricted QEMU to x86_64 only and is too old for LXC %if 0%{?rhel} == 5 %ifnarch x86_64 %define with_qemu 0 %endif %define with_lxc 0 %endif # RHEL-6 has restricted QEMU to x86_64 only, stopped including Xen # on all archs.

[libvirt] Uknown OS typehvm
by Fred Leeflang 28 Sep '09

Hello, I've had an older version of libvirtd/qemu running on Debian Lenny and had defined 4 virtual servers. I have the kvm and kvm_intel modules loaded (also compiled from source). I copied over my 4 config files from /etc/libvirt/qemu to /usr/local/etc/libvirt/qemu Now when I start up libvirtd -v: omega:~# libvirtd -v 20:17:38.877: warning : qemudStartup:566 : Unable to create cgroup for driver: No such device or address libvir: Domain Config error : unknown OS type hvm libvir: Domain Config error : unknown OS type hvm libvir: Domain Config error : unknown OS type hvm libvir: Domain Config error : unknown OS type hvm I'm trying to make sense out of the config files at this point but not very successful at it. I googled around a bit to see if others had this error message but most of the ones I found relate to not having the kernel modules loaded, which is visible in the 'virsh capabilities' output. Mine shows: fredl@omega:~$ which virsh /usr/local/bin/virsh fredl@omega:~$ virsh capabilities <capabilities> <host> <cpu> <arch>x86_64</arch> </cpu> <migration_features> <live/> <uri_transports> <uri_transport>tcp</uri_transport> </uri_transports> </migration_features> </host> </capabilities> This seems odd, this is from my /proc/cpuinfo: flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx rdtscp lm constant_tsc arch_perfmon pebs bts rep_good xtopology tsc_reliable nonstop_tsc aperfmperf pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 popcnt lahf_lm ida tpr_shadow vnmi flexpriority ept vpid So the processor is capable of it, however: fredl@omega:~$ virsh version Compiled against library: libvir 0.7.1 Using library: libvir 0.7.1 Using API: QEMU 0.7.1 *error: failed to get the hypervisor version error: Unknown failure * I'm guessing that's the problem and I realized that in the Debian package the qemu binary is named 'kvm' (may be a symlink) while mine's in -rwxr-xr-x 1 root staff 2286848 2009-09-26 19:31 /usr/local/bin/qemu-system-x86_64 So how does libvirtd try to find out the hypervisor version? how does it even know to use either Xen, qemu etc. ?

[libvirt] Re: OpenVZ : The restriction of domain name should be addressed
by Yuji NISHIDA 28 Sep '09

Hi Daniel, I didn't realize that I even did not follow the manner of XML. I have worked with this problem and got a small patch to handle "ID" in OpenVZ functionality. I found it is working well with the XML script included "ID" in domain tag. I am concerned that I had to edit the common file domain_conf.c. I still believe I should keep it away from this problem for compatibility with the others.

[libvirt] debug output?
by Fred Leeflang 28 Sep '09

28 Sep '09

I compiled libvirtd --enable-debug=yes so I can see what's going on, because I'm getting an error libvir: QEMU error : internal error unable to start guest: qemu: could not open disk image. How do I see any debugging output from libvirtd?

[libvirt] libvirt.py
by Fred Leeflang 27 Sep '09

27 Sep '09

Hello, Just getting started on this and checked out the source from git. Ran autogen.sh, configure, make, make install and it doesn't seem to automatically install libvirt.py. The generated Makefile in python/ has these lines commented out: #GENERATED = libvirt-export.c \ # libvirt.c \ # libvirt.h \ # libvirt.py Am I perhaps missing some python_includes? From what I can tell, WITH_PYTHON_TRUE only gets set to # if some includes are not there. I'm trying to build this on Debian Lenny with Python 2.5.2

[libvirt] Virsh migrate --live fails
by Subba Rao, Sandeep M (STSD) 25 Sep '09

25 Sep '09

Hi, I'm trying to live move a domU using virsh migrate command: [root@RHEL53Xen1 ~]# xm list Name ID Mem(MiB) VCPUs State Time(s) Copy_RHELVM3 1 511 1 -b---- 898.3 Domain-0 0 1507 4 r----- 133702.5 [root@RHEL53Xen1 ~]# virsh migrate --live Copy_RHELVM3 xen+ssh://15.154.102.20 error: server closed connection [root@RHEL53Xen1 ~]# However the same works using xm migrate --live. The source and the destination are RHEL 5.3 Xen hosts. Libvirt: [root@RHEL53Xen1 ~]# rpm -qa | grep libvirt libvirt-0.3.3-14.el5 libvirt-devel-0.3.3-14.el5 libvirt-cim-0.5.1-4.el5 libvirt-python-0.3.3-14.el5 Xen: [root@RHEL53Xen1 ~]# rpm -qa | grep xen xen-3.0.3-80.el5 xen-libs-3.0.3-80.el5 xen-devel-3.0.3-80.el5 kernel-xen-2.6.18-128.el5 I was earlier getting the error - "can't connect: Name or service not known". So, installed libvirt-0.6.4 as mentioned in the following link: https://bugzilla.redhat.com/show_bug.cgi?id=348861 After installing libvirt-0.6.4, I'm getting "server closed connection" error. Any help is much appreciated. Thanks, Sandeep

[libvirt] node device devicekit backend
by Dave Allan 25 Sep '09

25 Sep '09

I've been looking at implementing a libudev backed node device, and I noticed that the devicekit node device backend doesn't build. Since I believe DeviceKit is deprecated for this sort of use, and AFAIK the DeviceKit support was never functionally equivalent to the HAL support, I'm wondering if we can just drop DeviceKit support. It also drags in glib, which is a separate problem. Opinions? Dave

[libvirt] Miscellaneous fixes to build with -Werror
by Charles Duffy 25 Sep '09

25 Sep '09

HACKING suggests compiling with --enable-compile-warnings=error before submitting any patches; however, current master fails for me on this account (CentOS 5.3; gcc 4.1.2). Please see attached. I suspect most of these should be uncontroversial -- but wonder if perhaps virStrcpy uses would be better converted to virStrcpyStatic rather than adding virStrcpy to the symbol list as done here, and am curious about whether the need for explicit initialization to silence a warning regarding qemudSetLogging's log_level indicates a bug in the macro later used to assign that value.

[libvirt] Some problem with the save function
by Daniel Berteaud 25 Sep '09

25 Sep '09

Hi everyone. This is my first post to this list, so excuse me if it's not the right place to poste info like this. I've found some problems in qemu_driver.c in the latest versions of libvirt: - the first problem was also present in 0.7.0. If we run qemu guests unprivileged, we cannot use the save function (virsh save guestname /path/to/file). The reason seems to be that libvirt first create the destination file to write the header and the XML definition. The file is owned by root with 600 permission. Then, we ask qemu to append the dump of the memory (via the migrate exec: call) to this file. This part doesn't work because the qemu user cannot write to this file. So we endup with a file which only contains the header and the XML, and the guest is stoped :/ - the second problem is present since libvirt 0.7.1. Now that the saved file can be compressed, it seems we cannot save in a raw format any more. This is due to this part in the code (qemu_driver.c): if (STREQ (prog, "raw")) prog = "cat"; internalret = virAsprintf(&command, "migrate \"exec:" "%s -c >> '%s' 2>/dev/null\"", prog, safe_path); which result in "migrate \"exec cat -c >> safe_path 2>/dev/null\"" But cat doesn't support the -c argument, so once again, the save fails, as we end up with a save file which only contains the header and the XML definition. Unfortunately, my C knowledge is near 0, so I cannot correct this myself. - the third problem, is that restore doesn't work any more. I haven't dig it yet, but when I try to restore a guest using a saved file (uncompressed produced under libvirt 0.7.0), I've this error: virsh restore /tmp/guest.state error: Failed to restore domain from /tmp/guest.state error: internal error unable to start guest: Nothing interesting in /var/log/libvirt/qemu/guest.log: LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin HOME=/root USER=root LOGNAME=root /usr/bin/qemu-kvm -S -M pc -m 2048 -smp 4 -name guest -uuid 37b5937b-eacf-fda6-f4d0-33537d61b414 -monitor unix:/var/lib/libvirt/qemu/guest.monitor,server,nowait -localtime -no-reboot -boot c -drive file=/dev/data/guest,if=ide,index=0,boot=on -drive file=/var/lib/libvirt/iso/boot.iso,if=ide,media=cdrom,index=2 -net nic,macaddr=52:54:00:48:c4:ca,vlan=0,name=nic.0 -net tap,fd=25,vlan=0,name=tap.0 -serial pty -parallel none -usb -usbdevice tablet -vnc 127.0.0.1:0 -k fr -vga cirrus -incoming exec:cat The qemu process eats 100% of CPU during a few seconds, then stops (if I strace it during this time, I see a lot of error like bad file descriptor). Anyone have save/restore functions working with 0.7.1 ? Cheers, Daniel -- Daniel Berteaud FIREWALL-SERVICES SARL.
