[libvirt-users] libvirt issue while deploying a VM
by Zvi Dubitzky 16 Jun '14

16 Jun '14

Using libvirt under openstack I encounter a problem when launching a VM with multiple partitions (2 G image) , While a single partition can be launched successfully . The launch is done with Openstack. We are using in libvirtd.conf log_level=1 and log_outputs="1:file:/var/log/libvirt/libvirtd.log" we can see that in /var/log/libvirt/libvirtd.log appear the following error message and the VM is finally shutdown : 2014-06-11 14:47:26.166+0000: 12971: error : qemuMonitorIO:614 : internal error End of file from monitor ( file attached below) ( VM shutdown seen here) The host has enough resources( we see no complains) and the XML of the VM is : The libvirt version is: 0.10.2 The qemu-kvm version: 0.12.1.2 >From the internet we could not figure out a solution to the problem Any idea what is causing this error and how to overcome ? Thx Zvi Dubitzky Email:dubi@il.ibm.com

[libvirt-users] libvirt, openSUSE, SuSeFirewall2 and port forwarding
by Johannes Kastl 14 Jun '14

14 Jun '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello list, I thought I had already asked this question, but apparently I just started writing a draft mail and never sent it (at least I can't find it in the archives). Has anyone setup qemu VMs using libvirt on openSUSE, and has gotten port forwarding to work? I used on of the many scripts out there, that go into /etc/libvirt/hooks/qemu, and it is being called. Somehow it seems once in a while SuSefirewall2 just forgets about iptable rules set with this script. And sometimes they don't appear, even if the script is executed. Anyone else having the same issues? Any openSUSE users willing to try this? Thanks in advance! Regards, Johannes - -- What do Bud Light and sex in a canoe have in common? Both is fuckin' close to water. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) Comment: Using GnuPG with SeaMonkey - http://www.enigmail.net/ iEYEARECAAYFAlOcmAAACgkQzi3gQ/xETbJRwwCfZe3YKXfQG7O0aHFDvD6EwXus a/8An36n1L/pAWSTuue3w0GG2ovAsw07 =aLj5 -----END PGP SIGNATURE-----

Hi, Using libvirt how can we check the status of a remote/local host machine.. isAlive() method is giving true even if the internet connection is broken OR libvirt demon in the remote machine is being stopped. so isAlive() does not seems to be handy, Is there some other way to get the status of remote host..? Thanks -Sijo

[libvirt-users] about sharing the hugepage memory segment between the host and the container
by WANG Cheng D 12 Jun '14

12 Jun '14

Dear all, What I want to do is to share a hugepage memory segment between the host and a container (I am trying to use intel DPDK package in container). For a normal memory (4k page), the memory sharing can be achieved by memory-mapped I/O (mmap())method with the same disk file on the host exposed to the container (that is, the host and the container share the same disk file). my questions are: 1) Do I need to mount the hugetlbfs in host and container respectively? 2) According to my understanding, the exposed file that will be shared by the host and container must locate at the hugetlbfs mount point. Is this right? 3) According to my understanding, the mount point in the host doesn't necessarily to be the same as that of the container, as long as the mount point is exposed to the container, Is this right? 4) If I want to share the hugepage memory segment betwen two containers, what's the answers for 1) ? 5) According to my internet research, if use open() to open a file under the hugepage mount point, the mmap() will automatically return a pointer to the hugepage memory segment. Is this right? Apart from this, I cannot see other difference from memory-mapped I/O with the 4k page memory. Any answer will be highly appreciated. Cheng Wang

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
