[libvirt-users] SEV machines and memory pinning
by Boris Bobrov 04 Apr '19

04 Apr '19

Hello, I am working on implementing SEV support in OpenStack. There are some questions that came up in the discussion of the spec [0] [0] https://review.openstack.org/#/c/641994/ As far as i understand, the memory for SEV machines need to be pinned so that it doesn't migrate to swap and page migration. ROMS, UEFI pflash and video RAM should be pinned too. Initially we planned to use hard_limit of <memtune> element to pin the memory. However, from the discussion in the spec it seems that there is no way to determine a good enough value and that hard_limit should not be used at all. What should be used then? There is a suggestion to use something like this: <memoryBacking> <hugepages> <page size="2" unit="M" nodeset="1"/> </hugepages> <nosharepages/> <locked/> <source type="file"/> <access mode="shared"/> <allocation mode="immediate"/> </memoryBacking> Will it work? Are there any caveats we should remember about with this config? If we can use it, is there anything that would be redundant or not necessary for our case?

[libvirt-users] CfP VHPC19: HPC Virtualization-Containers: Paper due May 1, 2019 (extended)
by VHPC 19 04 Apr '19

04 Apr '19

==================================================================== CALL FOR PAPERS 14th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '19) held in conjunction with the International Supercomputing Conference - High Performance, June 16-20, 2019, Frankfurt, Germany. (Springer LNCS Proceedings) ==================================================================== Date: June 20, 2019 Workshop URL: http://vhpc.org Paper Submission Deadline: May 1, 2019 (extended) Springer LNCS, rolling abstract submission Abstract/Paper Submission Link: https://edas.info/newPaper.php?c=25685 Call for Papers Containers and virtualization technologies constitute key enabling factors for flexible resource management in modern data centers, and particularly in cloud environments. Cloud providers need to manage complex infrastructures in a seamless fashion to support the highly dynamic and heterogeneous workloads and hosted applications customers deploy. Similarly, HPC environments have been increasingly adopting techniques that enable flexible management of vast computing and networking resources, close to marginal provisioning cost, which is unprecedented in the history of scientific and commercial computing. Various virtualization-containerization technologies contribute to the overall picture in different ways: machine virtualization, with its capability to enable consolidation of multiple underutilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; OS-level virtualization (i.e., containerization), with its capability to isolate multiple user-space environments and to allow for their coexistence within the same OS kernel, promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; lastly, unikernels provide for many virtualization benefits with a minimized OS/library surface. I/O Virtualization in turn allows physical network interfaces to take traffic from multiple VMs or containers; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology is furthermore enabling virtualization of HPC infrastructures. Publication Accepted papers will be published in a Springer LNCS proceedings volume. Topics of Interest The VHPC program committee solicits original, high-quality submissions related to virtualization across the entire software stack with a special focus on the intersection of HPC, containers-virtualization and the cloud.

[libvirt-users] Clock skew on Win10
by Alex 03 Apr '19

03 Apr '19

Hi, I'm having a problem with significant clock skew on fedora29 with qemu-system-x86-3.0.0 and ibvirt-daemon-kvm-4.7.0. This is on my desktop and appears to happen between suspends of the host each night. It appears like the time just stops while the guest is suspended, of course, but then doesn't update once the guest is resumed. I'm pretty sure time is configured correctly on the Win10 guest. It's configured to be set according to Internet time and syncs with time.windows.com. How do I troubleshoot this further?

[libvirt-users] Virt-Lightning: a cloud-like CLI for libvirt
by Gonéri Le Bouder 27 Mar '19

27 Mar '19

Hi all, Tl;dr: Virt-Lightning uses libvirt, cloud-init and libguestfs to allow anyone to quickly start new VM. Very much like a container CLI interface, but locally. -> https://github.com/virt-lightning/virt-lightning To validate my Ansible roles, I was looking for a way to quickly start and stop my test environments. I was looking for an experience similar to what we have with the containers. Virt-lightning takes a distribution name as main input. The output is the IP address of a freshly deployed VM on which I can run my tests. Virt-Lightning uses master QCOW2 images with backing file and avoid the use of DHCP, this to speedup up the first boot. The configuration is done by cloud-init. The whole deployment is rather fast. For instance, I can deploy 3 VM in 25s (Lenovo T580). cloud-init is used to create the user account, inject the SSH keys, prepare the network configuration and resize the file system. Regards, -- Gonéri Le Bouder

[libvirt-users] virsh snapshot-create-as: change umask on snapshots
by Mircea Husz 23 Mar '19

I scripted the creation of snapshots and it works fine. Now I'd like to run the script as non-root. virsh snapshot-create-as --domain hq-live-v01 \ --name snappy \ --diskspec vda,file=/var/lib/libvirt/images/hq-live-v01.snappy,snapshot=external \ --diskspec vdb,file=/var/lib/libvirt/images/hq-live-storage.snappy,snapshot=external \ --disk-only --quiesce --atomic This fragment creates the snapshots, but get created with mode 0600: -rw------- 1 qemu qemu 393216 Mar 19 17:08 hq-live-storage.snappy -rw------- 1 qemu qemu 1048576 Mar 19 17:08 hq-live-v01.snappy The user account is in the libvirt group and has permissions to do everything except delete the files created by the snapshot, all I need is to get the snapshots created with 0660 mode. This is on a Centos 7.6 installation. What knobs do I need to turn to control the umask? Thanks, -Mike
