So I finally got it to work I was missing netmask value in the configuration Host only NIC enp0s3 TYPE=Ethernet BOOTPROTO=static NAME=enp0s3 UUID=71d4200e-199d-4d03-935d-6d2e88c41956 DEVICE=enp0s3 ONBOOT=yes IPADDR=192.168.56.101 NETMASK=255.255.255.0 NAT NIC enp0s8 HWADDR=08:00:27:49:5A:6C TYPE=Ethernet BOOTPROTO=dhcp DEFROUTE=yes PEERDNS=yes ...

If you don't mind rebooting, you can try Acronis True Image. It does cost money though, and I've had several experiences where it failed to create an image. You can use dd and gzip to create an image. It's actually quite fast, and gzip usually does a good job of keeping the image relatively small. dd if=/dev/sdX conv=sync,noerror bs=64K | pv | gzip -c ...

They're space-consuming. If you write 10% to a logical volume and then take a snapshot, the other 90% of that volume become unusable. Uh, no it isn't. The LVM snapshot presents two block devices, the origin LV (what you're snapshotting) and the snapshot LV. Only data that changes on either LV is actually written to the snapshot LV. You can mount the ...

To complete @Lambert's answer, there is also Btrfs (a linux file system) which allows to create and restore snapshots of subvolume of the file system. For differences between the two read this post on reddit. Btrfs is included into the linux kernel, and you can use it a you root filesystem. It seems possible to boot on it. Regarding to its "experimental" ...

You might have a look at the ZFS Fuse or ZFS on Linux project. The ZFS filesystem is capable of making snapshots and clones. I don't think it is possible to boot from ZFS for Linux but you might store your data/work within a ZFS pool. See also: http://zfsonlinux.org/ or search the Net for ZFS Fuse

Adding the Kali repositories would indeed change the /etc/os-release file. The version in Kali's repos is probably newer than the one in Debian's so apt downloaded it and replaced the one on your system. If you're very, very lucky, that's all that broke. Do not, I repeat not, ever mix repositories from different Linux distributions.

The guest operating system runs inside the host. The host has full control over everything that the guest does and everything that goes in or out of the guest. Thus any confidential information that becomes accessible to the guest is also accessible to the host. A rogue process on the host can access everything in the guest, assuming that it has sufficient ...

When both the Host and Guest OSes are turned off and the data is at rest on a storage device, is it any easier/harder to retrieve the encrypted file system? This scenario is similar to the security of a Truecrypt encrypted container in Host OS. If the Host is already off then accessibility can only be through personal access where more or less, ...

Simply configure a network adapter to 'bridged' mode, bridging it to your physical ethernet adapter enp0s3 (assuming that is the one connected to the Internet). Bridged mode will allow guest-host connectivity and guest-internet connectivity.

You need to include the drivers for the hardware that you've configured in your virtual machine. To keep things lightweight, put all the disks and CD devices on the same controller. Check the release notes for the list of drivers and the hardware they support. For example, if you choose a SATA AHCI controller (less hassle than IDE with its very limited ...

I'm not a grub2 expert (sorry) but try adding --skip-fs-probe to your grub-install line, I have found this prevents creation of /boot/grub/device.map which can cause booting to a grub prompt. I think that without this parameter grub-install, instead of doing what you tell it, thinks it is cleverer than you, and may do something different. Another thing is ...

have you check forwarding option ? sysctl net.ipv4.ip_forward try sysctl -w net.ipv4.ip_forward=1 note that unless told otherwise unix host do not forward from one interface to another. my thanks goes to http://www.ducea.com/2006/08/01/how-to-enable-ip-forwarding-in-linux/

You should set TCPKeepAlive yes in you /etc/ssh/ssh_config or ~/.ssh/config on your client, or /etc/ssh/sshd_config of your server. I am running VMs and ssh out an in of them, with this setting I have not had any recurring problems. You can also increase the loglevel by starting the server with -v, or (often easier) adding LogLevel DEBUG to your ...

The "DMAR: Disabling IOMMU for graphics on this chipset" message comes from the kernel, specifically http://lxr.free-electrons.com/source/drivers/iommu/intel-iommu.c?v=3.19#L4634. This quirk was introduced in https://lkml.org/lkml/2013/2/1/327 (the bugs linked from there give useful background information); apparently your chipset has bugs which cause ...

Yes, it should be possible with Virtualbox, by mapping the physical partition with a VMDK file. It is not possible via the GUI, but it can be done via the VBoxManage command. Below link might help: http://www.sysprobs.com/access-physical-disk-virtualbox-desktop-virtualization-software

As I remember, in VirtualBox you have at least two options for the virtual network interface: NAT Bridged If the subnet of the host is 192.168.0.XXX, and the virtual is 192.168.1.XXX ( or simply, different subnet) then the virtual card must be using NAT. If you want to use Bridge then the subnet of the host must be the same of the virtual. When do ...

Of course it is. Check this and this.

Found the problem -- maybe it will help someone in the future. My laptop does not have eth0, only wifi. I shutdown the VM and changed the bridged settings to wifi, then it works and I can access the ip address internally. From within the VM

To be able to use USB in your VM your user must be a member of the vboxusers group. To achieve this open a terminal window (in the host) and type sudo adduser <youruser> vboxusers Then log out and log in again.

Like pretty much everything else you can do with the VirtualBox GUI you can also do with the commandline tool VBoxManage. It is part of your installation. The command you're most likely looking for is VBoxManage snapshot 'MyVM' take "Snapshot of MyVM on $(date)" snapshot <uuid|vmname> take <name> ...

I was struggling with the same issue. After finally being able to solve the issue I HAVE to post it online so that this is of some help to the other novices around. I wanted to use putty to connect to my ubuntu on virtual box (comfort reasons,the VB is just weird.. I cant work unless it is on a proper terminal). Anyway, Make sure ssh client is installed ...
