Centos 7 AMI building scripts
by Andrei DRAGOMIR 30 Mar '15

30 Mar '15

Hello all, I tried to find the scripts that build the official CentOS 7 AMI images, but I cannot find them. Can somebody point me to a source repository for them ? I am trying to build my own CentOS AMIs and AMI building is turning out to be a dark art, and any pointers, or working source code would be really useful. Thank you, Andrei Dragomir. -- /A

Xen in a Box Proposal
by Gautam Malu 27 Mar '15

27 Mar '15

Hi everyone, I am a masters student at IIIT- Hyderabad, India. I have submitted my GSOC proposal for Xen in a Box. I would be great to have some suggestions especially about the porting of xapi on CentOS Abstract: My project goal is to deliver set of scripts preferrably in bash, along with all necessay packages to convert standared installers ISOs into customized ISOs which install CentOS 6 + xen + libvirt + 2 pv VMs running + network configuration. I also plan to deliver xapi rpms which can be used to build a custom installer ISO to install CentOS 6 + xen + xapi. Full proposal: http://www.google-melange.com/gsoc/proposal/public/google/gsoc2015/gautam_m… Best regards, Gautam Malu

Re: [CentOS-virt] [CentOS-devel] xapi for centOS 6.6
by Gautam Malu 26 Mar '15

26 Mar '15

Thanks Jon, it worked, I was able to build all the packages for xenserver on CentOS 6.6 final version. Here is the package list: https://gist.github.com/gautammaloo/7616cccbe8f5c85c196e I was wondering what packages would be necessary to use Xen with xapi, I already have xen with xl installed. Could we have a package like http://packages.ubuntu.com/precise/xcp-xe with which we can have xenserver running on CentOS, just by switching toolstack from xl to xapi.

virt-manager broken ?
by Günther J. Niederwimmer 25 Mar '15

25 Mar '15

Hello, with the last update for virt-manager I have a Problem with my CPU (XEON- SandyBridge) I have to disable the CPU Flag "invts", afterward I can install a KVM Guest! Now with the coming upgrade to centos 7.1 in the virt-manager the CPU Flag config is missing and I can't install a KVM Guest anymore :-(. Is this a know BUG? -- mit freundlichen Grüßen / best Regards, Günther J. Niederwimmer

libvirt errors after applying RPMS from 2015:X002
by rgritzo 24 Mar '15

24 Mar '15

Thanks for the info. I am trying to connect to the Xen hypervisor, via a localhost connection defined in the virt-manager configuration. here is the detail provided in the error dialog: ————————— Unable to open a connection to the Xen hypervisor/daemon. Verify that: - A Xen host kernel was booted - The Xen service has been started internal error: DBus support not compiled into this binary Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/connection.py", line 1168, in _open_thread self.vmm = self._try_open() File "/usr/share/virt-manager/virtManager/connection.py", line 1152, in _try_open flags) File "/usr/lib64/python2.6/site-packages/libvirt.py", line 105, in openAuth if ret is None:raise libvirtError('virConnectOpenAuth() failed') libvirtError: internal error: DBus support not compiled into this binary —————————— The hypervisor and VM’s work. If i start and manage VMs with virsh, the work fine. it just is the virt-manager that seems broken, but that is important for my operation. i just applied the patches to a second machine - just in case it was something about the first one - and the same results. i am not as versed in python debugging as i would like to be, so this will be a challenge. it sure seems like the issue is in the libvirtd library from the error messages - but i will keep poking at it as time permits and post here if i have any answers... thanks. r. > On Wed, Jan 28, 2015 at 09:54:54PM -0700, rgritzo wrote: > > folks: > > > > after applying the updated rpms from advisory 2015:X002 i am having problems with libvirtd, and with virt-manager. > > > > if i run libvirtd in the foreground and look at the error messages, the error i see is > > 2015-01-29 04:45:27.342+0000: 6477: error : virDBusGetSystemBus:1742 : internal error: DBus support not compiled into this binary > > > > Hmm, weird, it works OK for me.. > > > and virt-manager is unable to connect to the hypervisor. this started after i applied the subject patches. > > > > is this an issue with the recent versions of libvirt? > > anybody else seeing this behavior? > > > > What hypervisor are you trying to use?

by Gautam Malu 24 Mar '15

24 Mar '15

Hi, I am a masters student at IIIT Hyderabad, India. I am writing a GOSC proposal for CentOS organization. It's about delivering a custom installer ISO which delivers Xen 4.4 stack on CentOS 6. full proposal: http://www.google-melange.com/gsoc/proposal/public/google/gsoc2015/gautam_m… I want to port xapi on CentOS 6 as part of it. There has been some previous efforts to port xapi on CentOS 6 but nothing official, as follows: http://wiki.xen.org/wiki/XAPI_On_CentOS_6 https://github.com/JohnGarbutt/xen-api-devinstall http://wiki.xenproject.org/wiki/Ceph_and_libvirt_technology_preview i was wondering if there is any other project going on to port xapi on CentOS 6 > CentOS 6.3 with XenServer being fully open source now. Best regards, Gautam Malu
