Hi all, Does Xen dom0 mask CPU flags or what? I execute "cat /proc/cpuinfo" on bare-metal linux ,and get: +------------------------------------------------------------------------------------------------- | | flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 | clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt rdtscp lm | 3dnowext

Hi, firefox does not play h.264 videos on centos 7 so I need a flash plugin. But I see packages only for centos 6.x. What can I do? - Gergely

Hi there, some of my users use putty to connect to my server via ssh protocol. After some time they get the above error message, and it could be that my CentOS-side configuration caused this. Do anybody has experience with this problem? - Gergely

Thank you very much for getting back to me.

Hi there, I installed centos 7 -- it works great. What made me think is that installation took 1300 packages for a Desktop with some add-ons. As usual, there might be a solution for this already but I do not know it. Would it be possible to create one big package for a standard Desktop? Then an installation would not take ages. - Gergely

Hello, I'm trying to get the Android Emulator to run inside a kvm vm on CentOS-6. Apparently the latest Android Emulators cannot run without hardware acceleration so I am trying to get the vm to see the svm cpu flag. Host: $ grep model\ name /proc/cpuinfo | sort -u model name : AMD Phenom(tm) II X4 965 Processor $ grep svm /proc/cpuinfo | sort -u flags : fpu vme de pse tsc msr pae mce cx8

I just noticed something interesting with the pv_ops dom0 kernel that I built from Jeremy''s git tree. When I run ''cat /proc/cpuinfo'' the output shows the processors have 0.000 MHz. Everything runs fine I just thought it was interesting. processor : 3 vendor_id : AuthenticAMD cpu family : 16 model : 4 model name : AMD Phenom(tm) II X4

Hi, I have an fc17 server with an Opteron 6128 with a few fc17/16 guests. How can I be sure I'm best matching the guest CPU with that of the server? I've used virt-manager to create the guests, and it currently shows the processor is a "Phenom(tm) 9550 Quad-Core": processor : 1 vendor_id : AuthenticAMD cpu family : 16 model : 2 model name : AMD

Dear CentOs users, I have a centos server with nothing important at the moment, but I would like to install some web-based project management tool (trac for the curious) that would contain important data. And, as my network is growing the configuration of the server is becoming complex. I would like to have a proper backup so that I can restore the whole system easily, should any problem occur.

[OFF TOPIC] Hi Rowland Penny, Good morning from Singapore. Do you think my guide is well written?

Running a 3.14.4 x86-64 SMP guest kernel on qemu-2.0, with kvm enabled and -cpu host on a 3.14.4 AMD Opteron host, I'm seeing a reliable kernel panic from the guest shortly after boot. I think is happening in kvm_unlock_kick() in the paravirt_ops code: divide error: 0000 [#1] PREEMPT SMP Modules linked in: CPU: 1 PID: 0 Comm: swapper/1 Not tainted 3.14.4-guest #16 Hardware name: QEMU
