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

CentOS 7 AMI missing ENA support

24 Jan '18

Getting this API error trying to launch CentOS 7 (x86_64) - with Updates HVM AMI with AWS c5.large instance type in us-west-2: ==> amazon-ebs: Error launching source instance: InvalidParameterCombination: Enhanced networking with the Elastic Network Adapter (ENA) is required for the 'c5.large' instance type. Ensure that you are using an AMI that is enabled for ENA. AMI ID ami-a042f4d8, which is the 1801_01 version. Any ETA on this support, or is this an error in the new version that was released? Thanks, Jonathan

Xen 4.4 Immediate EOL
by Kevin Stange 22 Jan '18

22 Jan '18

Hi, I am very sorry to do this on short notice, but obviously Meltdown and Spectre are a lot more than anyone was really expecting to come down the pipeline. Xen 4.4 has been EOL upstream for about a year now and I have personally been reviewing and backporting patches based on the 4.5 versions made available upstream. Given that 4.5 is now also reaching EOL, backporting to 4.4 will become harder and I've already taken steps to vacate 4.4 in my own environment ASAP. Spectre and Meltdown patches most likely will only officially reach 4.6 and are very complicated. Ultimately, I don't think this is a constructive use of my time. Therefore, I will NOT be continuing to provide updated Xen 4.4 builds any longer through CentOS Virt SIG. If someone else would like to take on the job, you're welcome to try. Pop by #centos-virt on Freenode to talk to us there if you're interested. For short term mitigation of the Meltdown issue on 4.4 with PV domains, your best bet is probably to use the "Vixen" shim solution, which George has put into the xen-44 package repository per his email from two days ago. Vixen allows you to run PV domains inside HVM guest containers. It does not protect the guest from itself, but protects the domains from each other. Long term, your best bet is to try to get up to a new version of Xen that is under upstream security support, probably 4.8. -- Kevin Stange Chief Technology Officer Steadfast | Managed Infrastructure, Datacenter and Cloud Services 800 S Wells, Suite 190 | Chicago, IL 60607 312.602.2689 X203 | Fax: 312.602.2688 kevin(a)steadfast.net | www.steadfast.net

Centos 6 2.6.32-696.18.7.el6.x86_64 does not boot in Xen PV mode
by Dan 22 Jan '18

22 Jan '18

Is this now fixed in the latest release by updating the hypervisor, the same as CentOS 7? Or does this require something further? I came across https://access.redhat.com/solutions/3312501 which seems to suggest Redhat are working on resolving the issue, so if that's the case then maybe the solution implemented by CentOS is not the best option? Kind Regards, Dan

"Vixen" HVM shim package available in virt-xen-testing
by George Dunlap 18 Jan '18

18 Jan '18

To install the package: yum --enablerepo=virt-xen-VV-testing xen-vixen Where VV is '44', '46', or '48', depending on which version you're using. (It's the same package for all versions.) This will install the xen-vixen "shim" binary, as well as the pvshim-converter script. See XSA-254 [1] for detailed information about who should use it, why, and when. Please report both successes and failures here. :-) -George [1] https://xenbits.xen.org/xsa/advisory-254.html
