I have currently got a CENTOS7 guest inside windows 10 host and I am trying to install vagrant and Virtual box inside the CENTOS guest to create a kubernetes cluster for local development.
I have installed vagrant 2.1.1 and VirtualBox 5.2.12
When I am trying to
vagrant up
It says VT-X is not available.
I have turned on Virtualization in BIOS and I have checked windows features and HyperV is disabled/unchecked.
Also when I cat the /proc/cpuinfo , vmx is not in the flags

I would really appreciate any insight on how I can get this resolved.
You disabled hyper-v, this means that you are using alternative hypervisor(virtualbox?). I don't think that anything except hyper-v on windows supports nested virtualization.
You can give a try to hyper-v guest with centos(with enabled nested virtualization by command Set-VMProcessor -VMName <VMName> -ExposeVirtualizationExtensions $true) and run virtualbox with vagrant inside it.

I just upgrade our AWS EC2 instance from t2.xlarge to t2.2xlarge, so our instance now has 8 vCPU. Upon restarting the server, I run the command pm2 start src/app.js -i max -f and to my surprise, instead of my app running on 8vCPU, it now runs on 12 vCPU. At least that's what's the pm2 list displayed. What really happen here?
Here's the output of cat /proc/cpuinfo

Summary of what we talked about in the comments.
The output of cat /proc/cpuinfo tells us, that the instance actually has 8 CPU cores, which we can see from this line:
cpu cores : 8
That tells us AWS is giving you what you're paying for :-)
I don't know anything about pm2, but the docs tell me, that -i max in pm2 start src/app.js -i max -f tells pm2 to start as many worker processes as there are CPU cores.
It seems that somehow the CPU core detection has been messed up when you changed the instance type and it has chosen to add the new 8 cores to the 4 cores it already knew about to now give you 12 processes.
As a workaround you can explicitly set the number of worker processes to 8 like this:
pm2 start src/app.js -i 8 -f
I'm trying to create a minimalist setup for an ARM based virtual machine using qemu. I am following the following guide to do so.
I am running QEMU with the following command
qemu-system-arm -M vexpress-a9 -dtb ./linux-4.20.8/arch/arm/boot/dts/vexpress-v2p-ca9.dtb -kernel ./linux-4.20.8/arch/arm/boot/zImage -initrd rootfs.img --append "console=ttyAMA0" --nographic
I am, for some reason unable to see the login prompt. These are the boot messages

In buildroot, I've tried various configurations for the getty baudrate but to no avail. Please give me some pointers as to what exactly is going wrong. Currently I have tried with vt100, kernel selected baudrate as well as vt100, 115200 and it both fails
Update
As of now I have been able to see the login prompt after a slight modification to the command line arguments as follows:
qemu-system-arm -M vexpress-a9 -m 512M
-kernel linux-4.20.8/arch/arm/boot/zImage
-dtb linux-4.20.8/arch/arm/boot/dts/vexpress-v2p-ca9.dtb
-append "console=ttyAMA0,115200 ip=dhcp"

-netdev user,id=mynet0,net=192.168.160.0/24,hostfwd=tcp::2222-:22
-device virtio-net-device,netdev=mynet0
As you can see I've replaced -nographic with -serial stdio so I now see the QEMU GUI window separately (which is blank by the way) and I see the login prompt.What is going on here?
Additionally, I cannot use ssh to log into the VM from my Debian host (ssh has been selected in buildroot as you can see from the following log messages (which appear after my latest modification)
random: ssh-keygen: uninitialized urandom read (32 bytes read)

I've enabled root login by modifying the sshd_config file on the VM. I've tried ssh root#localhost:2222 as well as ssh root#192.168.160.9 but it just dies out (doesn't say if connection was refused or anything). I'm kind of lost here.
As per your instructions on the kernel command line (rdinit) the Linux kernel runs /sbin/init after boot as the first user process.
The one that is typically configured with Busybox (there are several options) will read a configuration file called /etc/inittab and act based on what is written there.
The execution of /etc/init.d/rcS, if at all, is performed from this file.
It is hard to pinpoint exactly what is happening but at a first step take a look at /etc/inittab. It is possible it is already mounting /proc.
At the very least I am guessing the errors regarding /dev/ttyy originates from directives in this file and can be silenced by editing it.
We are trying to boot linux in a xilinx system following the instructions in wiki-xilinx-linux.
After a lot of different tests, after had a look (among others) here, we have enabled the option "LOW LEVEL KERNEL DEBUGGING AND EARLYPRINTKs". Thanks to this we were able to see the following:

It seems that the Virtual File System tries to read from some unknown-block:
VFS: Cannot open root device "mmcblk0p2" or unknown-block(179,2): error -30
Googling, no solutions were found.
Has somebody some idea on how to solve this? Where can we have a look? Which parameter to play with?
Finally I solved all the problems I had (running linux on Zybo with a custom hw in the Programmable Logic). Yes, because I am a beginner, I found different problems:
1) One of the problem was in the .dts: the part with eFuse was compleatly missing. Xilinx committed another version of the .dts with the problem fixed.
2) Another big problem was with the bitstream: at the beginning I wanted to program the PL on Zybo with a running linux using: cat bitstream.bit > /dev/xdevcfg. Of course this is compleatly possible (I tested it) as it is explaned in [this wiki-page][1]. Problem: if you have a custom HW in in FPGA you have also its description in the device-tree. The kernel tries to initialize all the periferics connected to the PS but, of course, the PL is not yet connected!! The solution is to download the bitstream before, including it in the boot.bif in order to generate the boot.bin in the right way:
image : {
[bootloader]fsbl.elf
bitstream.bit
u-boot.elf
devicetree.dtb
uramdisk.image.gz
uImage.bin // currently bootgen requires a file extension. this is just a renamed uImage
}
of course using: bootgen -image boot.bif -o i boot.bin.
There were other little problems and I will try to add a list in future editing-revision of this answer.
UPDATE:
to solve the problem described in the question, if there are no additional problems/errors, should be enough to add the bootargs the option rootdelay=3 (rootdelay — Time to delay before attempting to mount the root filesystem).
This can be necessary because u-boot tries to access the SD too fast and the SD is not ready yet.
You have it set to use the root filesystem on mmcblk0p2 - the second partition of your SD-card. If the filesystem is in fact placed there, you have to verify that the kernel has support for what the partition was formatted with (e.g. ext3).
Is this a prebuilt image or one you built yourself?
If you use the command petalinux-config before building, you can change settings for where to store the filesystem.
Btw, this is a very common problem so you should find lots of info if you use the right terms when you google it.
I am trying to enable multiple MSI irq lines in a kernel module. I am operating in RC mode. The problem is when I call pci_enable_msi_block() it will not allocate more than 1 MSI. If I call pci_enable_msi_block(dev, 32) it will return 4 (which I assume should mean I can use 4 MSI). I then call pci_enable_msi_block(dev,4) and it returns 1.
Here is an output from $lspci -v after insmod Custom_module.ko but with only a successful enable of 1 MSI

How do I go about using more than 1 MSI. I can use JTAG to edit the Enable_MSI registers and then the EP can trigger the MSI, but there is no handler dedicated to these IRQs.

I also tried the qemu_arm_versatile_defconfig with the same qemu boot

wrong, and any tips?

Back in late 2011, we had problems with the IA32 CodeSourcery toolchain, but they should now be fixed.
Try to use:
root=/dev/sda1
in boot script as sda1 corresponds to the first partition of the sda.
Have you tried to disable SELinux as mentioned in this thread?? Perhaps it might fix it.
