ovirt-engine package for oVirt 4.1.x
by C. L. Martinez 16 May '18

16 May '18

Hi all, I am trying to install oVirt 4.1.x from centos repos but it seems ovirt-engine doesn't exists. But instead, ovirt-hosted-engine-setup exists? Is ovirt-engine package removed? In official oVirt repos, exists. Thanks.

Xen 4.6.6-9 (with XPTI meltdown mitigation) packages making their way to centos-virt-xen-testing
by George Dunlap 04 May '18

04 May '18

I've built & tagged packages for CentOS 6 and 7 4.6.6-9, with XPTI "stage 1" Meltdown mitigation. This will allow 64-bit PV guests to run safely (with a few caveats), but incurs a fairly significant slowdown for 64-bit PV guests on Intel boxes (including domain 0). If you prefer using Vixen / Comet, you can turn it off by adding 'xpti=0' to your Xen command-line. Detailed information can be found in the XSA-254 advisory: https://xenbits.xen.org/xsa/advisory-254.html Please test and report any issues you have. I'll probably tag then with -release tomorrow. 4.8 packages should be coming to buildlogs soon. -George

Contributing Hyper-V/Azure packages
by Stephen Zarkos 24 Apr '18

24 Apr '18

Hi All, I'm interested in contributing to Virt-SIG with packages focused on Hyper-V/Azure support, i.e. kernel packages with additional patches and build configurations tuned for Hyper-V. There are some advantages these packages can bring to CentOS users - - Access to the latest features and fixes - Reduced boot time - Smaller memory footprint Of course all the new features/fixes are already upstream in the mainline kernel, but the aim here would be to backport them for easy consumption. Any questions about this sort of contribution? I'd love to see this happen. Thanks! Steve

CentOS 7 / Xen 4.6 on UEFI system?
by Chris Wik 27 Feb '18

27 Feb '18

Wondering if anyone has managed to get Xen to boot from UEFI? We have a relatively new server with a Supermicro X11SSH-F mainboard with an M.2 SSD. If we switch the boot mode to Legacy in the BIOS no boot devices show up. The vendor says this is because M.2 SSD is only supported in UEFI mode. We even tried installing some spinning SATA drives and a USB thumb drive but those don't show up as bootable either in legacy mode. Trying to boot Xen 4.6 from the centos-release-xen repo results in: Loading Xen 4.6.6-8.el7 error: can't find command 'multiboot'. Loading Linux 4.9.75-29.el7.x86_64 ... error: can't find command 'module'. Loading initial ramdisk ... error: can't find command 'module'. Press any key to continue ... From what I've read we need to compile xen.efi and boot it natively. I found this: https://wiki.xenproject.org/wiki/Xen_EFI#Compiling_Xen_as_EFI Which sugests binutils doesn't support PE (EFI), which looks to be the case with the stock version on CentOS 7, note missing i386pe from the list of supported emulations: # ld -V GNU ld version 2.25.1-32.base.el7_4.2 Supported emulations: elf_x86_64 elf32_x86_64 elf_i386 i386linux elf_l1om elf_k1om I downloaded binutils 2.30 from http://ftp.gnu.org/gnu/binutils/ and built it with: yum -y groupinstall "Development Tools" tar xzf binutils-2.30.tar.gz cd binutils-2.30 ./configure --enable-targets=x86_64-pep make make install Now I have a version that supports i386pe: # /usr/local/bin/ld -V GNU ld (GNU Binutils) 2.30 Supported emulations: elf_x86_64 elf32_x86_64 elf_i386 elf_iamcu i386linux elf_l1om elf_k1om i386pep i386pe However at this point I guess I need to rebuild Xen from source in order to obtain the xen.efi binary, and I'm not sure how to do that. Am I on the right path? Any tips on how to recompile Xen to get xen.efi binary? Or am I barking up the wrong tree? Thanks in advance for any advice.

AWS Official AMI's with ENA Support
by Brian Lancaster 26 Feb '18

26 Feb '18

Hi, So whats the deal here guys? Is CentOS not going to start flagging the AMI's for AWS with the 'EnaSupport = True' on the latest images being created? Having this flag is the only way to take advantage of the newer m5 and c5 instance family types. Seems only `ami-02e98f78` supports ENA in 'US-EAST-1' to date and all since then do not. Would like someone to explain why this hasn't happened yet. -- Brian Lancaster

Kimchi and noVNC
by Jean-Marc Liger 23 Feb '18

23 Feb '18

Hi, I've rebuild Kimchi/Wok 2.5.0 based on ClearOS packages. I've also upgraded noVNC 1.0.0. Unfortunatly the QEMUExtendedKeyEvent which fixes French keyboard's detection doesn't work for me at the moment. But maybe, the problem is located in my QEMU 2.11.0 implementation. If someone want to digg his own way ? https://copr.fedorainfracloud.org/coprs/jmliger/virt7-upstream/builds/ *Jean-Marc LIGER Ingénieur Systèmes et Réseaux de Communication * FACULTÉ DE MÉDECINE Direction Technique, Informatique, Réseaux et Multimédia 15 rue de l’École de Médecine – 75270 Paris cedex 06 Tél : +33 (0)1 76 53 00 71
