To add to @Goyuix's answer, this script will export all the Oracle .cers in the current directory with the start of the thumbprint in the filename: $type = [System.Security.Cryptography.X509Certificates.X509ContentType]::Cert dir cert:\LocalMachine\TrustedPublisher | where { $_.Subject -like "*Oracle*" } | ForEach { ...

It seems that the network adapter for VirtualBox can be restarted easily at the command prompt by running something like the following (will be a little different on your system) sudo ifconfig vboxnet1 down sudo ifconfig vboxnet1 up Note that you'll have to replace vboxnet1 with whatever your virtual network adapter is for VirtualBox, which you can find ...

To be able to ping each other, you must use bridged connection mode. NAT mode will always block in the incoming PING request as if you're behind your Router's NAT. Please make sure use the same IP Network both in your host and your virtual machine to make sure they can communicate. When both of your machine can access internet but unable to do ping to each ...

I just solved a similar issue. Problem: The command to login to the guest development environment, vagrant ssh, was timing out. It routinely works fine on another host machine. Debugging steps: In the Vagrantfile, I enabled the Virtualbox GUI (as recommended in another answer) to see what was causing the timeout. Ubuntu was asking for a login and ...

So you want the virtual machines to expand their own virtual disk storage allocation? To the best of my knowledge this cannot be done. It would completely violate the principle of the VM being sandboxed from the host. If you can RDP to the host machine then you could do it from there; you wouldn't need physical access (unless you need to add more physical ...

I don't know if I understood your question correctly but, using Remote Desktop on Windows, you can always use a local resource, like a printer but also a disk drive or a USB drive, in the machine you are connecting to. It's in the "Local resources" tab (click "More" to choose a disk drive).

This is also not ideal, but I successfully created a vagrant base box from scratch using these instructions: See here: http://thornelabs.net/2013/11/11/create-a-centos-6-vagrant-base-box-from-scratch-using-virtualbox.html Make sure to go to the Network tab and change the Adapter type (in Advanced) to "Paravirtualized Network (virtio-net)" Also remember to ...

I've been faced with this situation myself. The problem isn't resizing the virtual disk (*) but rather resizing the root partition & the file system on the virtual disk. Resizing a mounted file system or growing a live partition at runtime is not possible. I solved the problem by booting the vm from a Ubuntu LiveCD (in try me mode). I managed this by ...

The general approach to solving this problem would be to interrogate the hosts rather the VMs. The VMs in theory have no idea that they are VMs. To that end the command VBoxManage list runningvms on a given host should display all running VMs on that host. If you NEED a purely networking solution to the problem you will need some pretty fancy switches ...

No. There is no way of doing this*. There is no such thing as a route for arp. It's locally-significant only. *... unless you control the virtualization layer in such a way that you can push that information into the guests.

So, as expected the problem is missing drivers. There are multiple drivers that can cause it. In my case - the VirtualBox with SCSI HardDrive should have the following drivers set: Device Drivers -> Block Device -> Initial RAM disk (initrd) Support Device Drivers -> Block Device -> RAM disk support Device Drivers -> SCSI device support -> SCSI device ...

Fedora uses firewalld as the firewall these days. Stopping iptables directly is not the correct way to stop the firewall. Try systemctl stop firewalld.service instead. You have started the NFS service on the Fedora VM haven't you? You'd do that by running systemctl start nfs.service on the VM. If you've changed the /etc/exports file since starting the ...

Alright figured it out. This line from the access.log is what cued me in: 192.168.0.119 - - [25/Sep/2014:20:56:55 -0500] "help" 302 0 "-" "-" Apache was being redirected by the application that I was trying to install ( Magento ). I had to edit the base_url in the database, because it was set to localhost.

Resizing a filesystem in your scenario (virtual machine with a linux guest with LVM) consists of the following steps: expand the "physical" disc in VB (you already did this) expand the partion to take up the new space (you already did this) Now you get into the realms of LVM: expand the "physical volume": pvresize /dev/sda5, this will also add to the ...

Check your /etc/redis/redis.conf, and make sure to change the default: bind 127.0.0.1 to bind 0.0.0.0 Then restart your service: sudo /etc/init.d/redis restart You can then now check that redis is listening on non-local interface with: redis-cli -h 192.168.x.x ping if you get PONG it's ok.
