You can use Debian on Hyper-V with 4 vCPU support.

1) Install a clean Debian 5.0.6

2) Do following:

1
2
3
4
5
6
7
8

apt-get update
aptitude update
wget -c http://www.yusufozturk.info/linux/linux-image-2.6.36-hyperv-debian.x86_64.deb
wget -c http://www.yusufozturk.info/linux/linux-headers-2.6.36-hyperv-debian.x86_64.deb
apt-get install build-essential
dpkg -i linux-image-2.6.36-hyperv-debian.x86_64.deb linux-headers-2.6.36-hyperv-debian.x86_64.deb
echo -e "hv_vmbus\nhv_storvsc\nhv_blkvsc\nhv_netvsc" >> /etc/initramfs-tools/modules 
update-initramfs –u –k 2.6.36-hyperv

That’s it. Reboot your server with new kernel. Now you can use synthetic ethernet and 4 vCPU.

Also integrated shutdown is available:

You can use CPU stress tool for tests.

Hyper-V Linux Integration Component (aka LIC) v2.1 kurulu olan Centos 5.x üzerinde kernel update yaptığınızda yeni kernel üzerinde “Kernel Panic” almanız söz konusu olabilir. Kernel Panic sorununu çözmek için aşağıdaki adımları uygulamanız gerekmektedir.

1. Öncelikle makinayı eski kernel ile boot edin.

2. Aşağıdaki komutu çalıştırın.

yum update

3. Güncelleme tamamlandıktan yeni yüklediğiniz kernel’ın tam ismini not edin.

cd /lib/modules && ls

4. Benim yeni kernel’ımın 2.6.18-194.17.4.el5 olduğunu görüyorum. Sizdeki kernel’a göre aşağıdaki komutu çalıştırın.

grep -ilR uname * | xargs sed -i 's/uname \-r/echo "2.6.18-194.17.4.el5"/g'

5. Driver’ı yeni kernel için tekrar derleyin.

make && make install

Bu işlemler sonrası yeni kernel’ı açabiliyor olmalısınız.

You may get this error when you do kernel compile in Debian 5.0.x versions.

To fix this issue, navigate to your kernel directory:

cd /usr/src/linux-*/debian/ruleset/misc

Open version_vars.mk:

nano version_vars.mk

Change the file like the below:

UTS_RELEASE_HEADER=$(call doit,if [ -f include/generated/utsrelease.h ]; then  \
	                       echo include/generated/utsrelease.h;            \
	                   else                                            \
                               echo include/generated/utsrelease.h ;              \
	                   fi)

Then you can compile your new kernel.

In Centos 5.5, when you do “yum update”, you may get this errors:

That stops update process. To resolve conflicts, you should disable rpmforge repo. To disable it:

1
2

cd /etc/yum.repos.d/
nano rpmforge.repo

Change following entry:

enabled = 1

with

enabled = 0

Then you can do yum update.

In one of the Technet question, John said:

“When the Hyper-V role is enabled, the physical machine becomes a virtual machine known as the parent partition. The virtual machines are called child partitions. Each partition is isolated from the other. Task Manager in any partition shows only the load on the cpus in that partitions. If the child partitions are heavily taxing the physical cpus, Task Manager in the parent partition shows little cpu activity (assuming you don’t have some heavy load in the parent, which you shouldn’t – best practice is to not have things running in the parent).”

So that means, looking task manager is not a way to know exact resource usage of Hyper-V. If you need to monitor CPU usages of child partitions (virtual machines), you should use Perfmon or.. yes, Powershell :) I wrote a little script to see CPU usages. In my environment, we use Windows Server 2008 with Powershell v1, so I have to write it in version 1. But If you have Powershell v2, you surely can use Get-Counter command.

Function HyperVCPU($InstanceName)
{
$CategoryName = "Hyper-V Hypervisor Virtual Processor"
$CounterName = "% Guest Run Time"
$PerfCounter = New-Object System.Diagnostics.PerformanceCounter($CategoryName, $CounterName, $InstanceName)
$Result = $PerfCounter.NextValue()
$Result = $PerfCounter.NextValue()
$Result
}
 
Function ShowPerfmon
{
$PerfMon = New-Object System.Diagnostics.PerformanceCounterCategory
$PerfMon.CategoryName = "Hyper-V Hypervisor Virtual Processor"
$Instances = $PerfMon.GetInstanceNames()
Foreach ($Instance in $Instances)
{
$CPU = HyperVCPU $Instance
$Results = New-Object Psobject
$Results | Add-Member Noteproperty Name $Instance
$Results | Add-Member Noteproperty CPU $CPU
$Results
}
}
 
ShowPerfmon

But be careful. You need to run Powershell as an Administrator to reach perfmon counters. If not, you will get “Category does not exist” error.

Virtuozzo Container’ında bir problem olması durumunda, container stopping durumda kalabilir.
Bununla birlikte start ve stop butonları da işlevselliğini yitirebilir.

Bu durumda container’ı destroy etmeyi denemek de sorunu çözmeyecektir.

Aynı şekilde yedekten geri dönmeye çalıştığınızda da aynı hatayı alabilirsiniz.
Yine çalışan servisleri kontrol etmeye çalıştığımızda, aşağıdaki gibi bir hata almanız da mümkün.

Konsolun işe yaramaması nedeniyle işlemleri CMD üzerinden gerçekleştirmeliyiz.
Bunun için aşağıdaki komutları çalıştırmanız yeterli olacaktır;

Bu işlemler sonrası panel üzerinden işlemleri yürütmeye devam edebilirsiniz.

Hello everyone,

Recently I announced new Wimp Server version for our PHP on Windows project.
New version is officially supported by Microsoft Turkey.

So What’s new?

Some screenshots from new Wimp Server Installer Gui:

As you see, you have different installation options. One of them is Manually Install, other one is Unattended Install. If you want to install MySQL manually, you can choose. Also you can choose x86 or x64 versions of products.

There is no automatic update feature for Wimp Gui yet but will be soon. (maybe in v4)
