by Karanbir Singh 29 Feb '16

hi, I just noticed that yum install xen does not pull in the xen kernel on c7, is this by design ? -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

XSAs 170 and 154, repository layouts, and centos-release-xen 8-1
by George Dunlap 24 Feb '16

24 Feb '16

I have the following packages going through the CBS: * A CentOS 7 xen-4.6.1-2, with XSAs 170 and 154 * A CentOS 6 xen-4.6.1-2, with XSAs 170 and 154 * A CentOS 6 xen-4.4.3-11, with XSAs 170 All these should show up in mirrors hopefully sometime later today. As usual, please report any problems here. Xen 4.4 only has XSA 170 because at the time the embargo was lifted, I didn't have a suitable backport of XSA-154. It's only applicable when PCI-passthrough is in effect, so it's not that critical. Additionally, we've moved to the new repository layout. Repositories will now be tagged with the release; so C6 will have xen-44 and xen-46, and C7 will have xen-46. For now, the existing xen/ repository will be a symlink -- to xen-44 for C6 and to xen-46 for C7. There will be new centos-release-xen packages coming down the line. As described elsewhere: * centos-release-xen-44 will always point to the xen-44 repository * centos-release-xen-46 will always point to the xen-46 repository * centos-release-xen will (normally) point to whatever the most recent release is. For the time being, the C6 version of centos-release-xen will remain pointing to xen-44. These packages can be installed at the same time; yum will choose the most recent release of all available. = What you need to do (C6 users only) = * If you want to stay on xen-44: yum install centos-release-xen-44 yum remove centos-release-xen * If you want to update to xen-46 and stay there until you choose to update: yum install centos-release-xen-46 yum remove centos-release-xen * If you want to update to xen-46, and also get further updates automatically: yum install centos-release-xen-46 = What you need to do (C7 users) = Much less urgent, since we don't plan to upgrade until 4.8, but: * If you want to stay on 46 until you choose to update: yum install centos-release-xen-46 yum remove centos-release-xen * If you want to get further updates automatically: Do nothing, you're already set.

Hi, I've got an LXC container running. Essentially, only core, and openssh-server installed inside the container. Got a shell with lxc-attch -n "containername", but unable to run system-config-firewall. Any ideas, what might be wrong?

Garbled screen after RAM Scrub on boot
by Francis Greaves 23 Feb '16

23 Feb '16

Dear All I am using Centos 7 with Xen 4.6 on a Dell Poweredge T430 When the machine boots, after the 'Scrubbing Free RAM' message, I get a screen filled with little white squares until the login prompt, so I cannot see what is happening as the machine boots. Also there is nothing on the screen when I reboot. My /etc/default/grub is GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_CMDLINE_LINUX="crashkernel=auto rhgb intremap=no_x2apic_optout" GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=13312M,max:14336M dom0_max_vcpus=6 dom0_vcpus_pin" GRUB_GFXMODE=1024x768 GRUB_GFXPAYLOAD_LINUX=keep GRUB_CMDLINE_LINUX_XEN_REPLACE_DEFAULT="console=hvc0 earlyprintk=xen nomodeset" I have tried setting (for a 1024x768 resolution) vga=792 in the GRUB_CMDLINE_LINUX and commenting out GRUB_GFXMODE and GRUB_GFXPAYLOAD_LINUX, but this makes no difference What am I doing wrong? Regards Francis

ssh access to vmware vm from outside
by Eric Tagtick 21 Feb '16

21 Feb '16

Hi, I have a centos 7 host server, which hosts vmware vms with various Os. I want to reach a ubuntu 14.04 vm through ssh and x2go (ssh as well). What I did. 1/ open a 2296 port in firewalld. 2/ add 2296=internalvmip:22 in tcp section of /etc/vmware/vmnet8/nat/nat.conf (vmnet8 being the vms network) >From the host server I can ssh the vm, but from outside, a ssh -p 2296 user@hostserverip gives me a connection refused. I tried a firewall-cmd --zone=external --add-forward-port=port=2296:proto=tcp:toport=22:toaddr=internalvmip but it does not change anything. What am I missing ?
