Hello, There is a vulnerability described in the gnuTLS library which is used in libvirt: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3466 We are using libvirt 0.8.7 on Windows so my question is: Is there already a windows version with a newer gnuTLS library which has a fix for the mentioned vulnerability? --- Sent from my Fujitsu Lifebook E782 With best regards Alfred Boehme Senior Developer PSO PM&D SV E SW 4 [cid:image001.gif@01CF8617.647717D0] FUJITSU Mies-van-der-Rohe-Str. 8, 80807 Munich, Germany Tel: +49 (89) 62060 2990 Mob: +49 (171) 62060 329 2990 E-mail: Alfred.Boehme(a)ts.fujitsu.com<mailto:Alfred.Boehme@ts.fujitsu.com> Web: ts.fujitsu.com<http://ts.fujitsu.com/> Company details: Fujitsu Technology Solutions GmbH / ts.fujitsu.com/imprint<http://ts.fujitsu.com/imprint.html> This communication contains information that is confidential, proprietary in nature and/or privileged.

by vivek hari 10 Jun '14

10 Jun '14

Hi, I tried to create a VM in ESXi 5.5 and to assign the interface to a Distributed switch portgroup. But i failed to achieve it. When i define a VM with distributed portgroup , i cannot see that distributed portgroup getting assigned to the VM network interface. My libvirt version is 0.10.2 I wish to know whether the libvirt supports assigning interface to a distributed port group ? If so how to proceed with it. Thanks, Vivek

Thanks for your help. My teacher advised me to use the "load_kld cpufreq" command and it resolved the problem. Tomasz Kowal

Dear libvirt experts, I can not instantiate even a simple machine when using the 'vbox' hypervisor: s14% virt-install --connect=vbox:///session --virt-type vbox --name vtest --memory 500 ERROR cannot obtain CPU freq: No such file or directory s14% virsh -c vbox:///session błąd: cannot obtain CPU freq: No such file or directory (1) How to fix this error?

[libvirt-users] Libvirt Python Bindings - Remote Connection using openAuth.
by Sijo Jose 06 Jun '14

06 Jun '14

Hi, I am using libvirt with python binding, and I want to connect to a remote host. I was able to connect after making ssh certificate, but It is not applicable for my project. So I want to use openAuth() method, but I could not succeed connecting to a remote host using it. Here is my code ------------------------ import libvirt USER = "root" PASS = "mypasswd" def authcb(credentials, user_data): for credential in credentials: if credential[0] == libvirt.VIR_CRED_AUTHNAME: credential[4] = USER elif credential[0] == libvirt.VIR_CRED_PASSPHRASE: credential[4] = PASS return 0 auth = [[libvirt.VIR_CRED_AUTHNAME, libvirt.VIR_CRED_PASSPHRASE], authcb, None] conn = libvirt.openAuth("qemu+ssh://192.168.1.21/system", auth, 0) print conn.getHostname() ------------------------------- *If there is something wrong, how am I supposed to use it.* If its not the right place to get libvirt-python related help, from where can I get it. Regards Sijo

[libvirt-users] Updating domain XML issue
by Brian Rak 05 Jun '14

05 Jun '14

I'm trying to unmount a guest cdrom using libvirt_domain_update_device (via php-libvirt). The guest cdrom is currently mounted via Ceph, via this XML: <disk type='network' device='cdrom'> <driver name='qemu' type='raw'/> <auth username='cdroms'> <secret type='ceph' uuid='XXXX'/> </auth> <source protocol='rbd' name='cdrom/test'/> <target dev='hdc' bus='ide'/> <readonly/> <address type='drive' controller='0' bus='1' target='0' unit='0'/> </disk> In order to unmount it, I'm trying to use this XML: <disk type='file' device='cdrom'> <driver name='qemu' type='raw'/> <target dev='hdc' bus='ide'/> <readonly/> <alias name='ide0-1-0'/> <address type='drive' controller='0' bus='1' target='0' unit='0'/> </disk> However, I'm getting an error from libvirt: 'internal error: invalid secret type 'ceph''. I suspect this is because it's still trying to use the authentication information from the old cdrom definition. How do I convince it to not do this? I've tried specifiying an empty <auth/> block, but that generates it's own error ('missing username for auth')

[libvirt-users] Problem connecting to hypervisor
by Vikas Kokare 03 Jun '14

03 Jun '14

I am trying to establish a connection (using virsh command) to a couple of hypervisor hosts, both on SLES 11.3 environments. The host from where i am making both the connections is a SLES 10.4 instance. *kvmh911351246:~ # virsh -c qemu+ssh://9.113.51.247:22/system <http://9.113.51.247:22/system>libvir: XML-RPC error : authentication requirederror: failed to connect to the hypervisor* The SSH authentication to hypervisor host 9.113.51.247 has already been established. *kvmh911351246:~ # ssh root(a)9.113.51.247 <root(a)9.113.51.247>Last login: Tue Jun 3 11:31:56 2014 from scm-kvmh2-rhel6 SLES11-51-247:~ #* Hence the cause of the authentication failure is not clear. The second connection to another SLES 11.3 host looks like *virsh # connect qemu+ssh://9.121.58.19:22/system <http://9.121.58.19:22/system> bash: socat: command not foundlibvir: Remote error : socket closed unexpectedlyerror: Failed to connect to the hypervisor* where the cause of the error is entirely different. The libvirt packages available on these environments are *9.113.51.247 (SLES 11.3)* *libvirt-cim-0.5.12-0.7.16libvirt-1.0.5.1-0.7.10libvirt-python-1.0.5.1-0.7.10libvirt-client-32bit-1.0.5.1-0.7.10 libvirt-lock-sanlock-1.0.5.1-0.7.10libvirt-client-1.0.5.1-0.7.10* *9.121.58.19 (SLES 11.3)* *libvirt-cim-0.5.12-0.7.16libvirt-client-1.0.5.1-0.7.10libvirt-python-1.0.5.1-0.7.10 libvirt-1.0.5.1-0.7.10* *9.113.51.246 ( SLES 10.4)* *libvirt-python-0.3.3-18.22.1libvirt-devel-0.3.3-18.22.1libvirt-0.3.3-18.22.1* How can these connection failures be debugged? Is there a way to know more information about them?
