Running virtual webserver using VirtualBox offline

I hope this is the right forum.
I have a virtual ubuntu webserver running on my MacBook (Leopard) using VirtualBox. When I use the wireless router for my home network everything works fine. For the installation see: http://blog.johan-mares.be/ict/linux/installing-a-virtual-ubuntu-lamp-server-on- mac-os-x-using-virtualbox/
The moment I want to use the network my MacBook provides (192.168.2 subnet) by selecting the en0 Ethernet as host interface in VirtualBox so I can use it when I am offline it doesn't work anymore (whether I am offline or online via Airport): I cannot ping or ssh from my MacBook to my virtual server (whether is has a dhcp or static network config): I get
ping: sendto: Cannot allocate memory
or
ssh: connect to host 192.168.2.5 port 22: Cannot allocate memory
When I use dhcp config in my virtual ubuntu server, every time I restart my virtual the ip address is incremented by 1, but still I cannot connect to it.
I haven't got a clue where to look or what to look for.
Any advice would be welcome.

Cannot create a domain using VirtualBox with W2012 DataCenter guest OS

Hello there,
I've been trying to troubleshoot this issue for days now and it has got me completely stumped. It's also brought my studying to a grinding halt, which is very frustrating. Any help would be very much appreciated!
I'm studying for MCSA and have built a home lab using VirtualBox. At one point, I had everything running smoothly with a Bridged setup in VirtualBox. I had a domain created with DNS on two W2012 servers. All good so far and it worked a treat!
I then hit a certain exercise in the study book that required creating a forest from scratch so I uninstalled all AD/DNS roles on all servers and tried to configure a forest but now I cannot get back to my prior good state. Every time I try and install/configure
AD DS, I get three errors in BPA results:
1. Enable computer and user accounts to be trusted for delegation
2. Access this computer from the network granted to the appropriate security principals
3. This forest should be correctly configured to synchronize time
Also, when I try to connect to AD Admin Centre, it states: Cannot connect to any domain. Trying to connect another W2012 server to the domain also fails spectacularly.
Having done some research, it seemed like the right network config is very important to successfully setting up a W2012 domain, so I followed this guide to the letter, using pfsense:
http://www.slideshare.net/rpainter/how-to-create-a-windows-server-2008-virtual-lab-using-virtualbox
Still, no joy and exactly the same errors/issues. Any ideas?

"connect to AD Admin Centre or DNS Manager for corp.contoso.com without an error stating that the domain cannot be contacted."
From where are you trying to connect? It sounds like you are trying to connect to these across the network from another machine. In that case, it is a networking issue. Can the remote machine from which you are trying to connect ping the
DC by means of IP address (not DNS)?
corp.contoso.com implies that you created a forest root with the name contoso.com. You could have all sorts of machines in that root, because it is really just a domain. Then, after creating a domain called contoso.com, you created child domain
that was underneath contoso.com, and you called that domain corp.contoso.com. Now, if you had a system in the forest root that had the name corp, with the domain name attached to that, you would have a fully qualified domain name of corp.contoso.com.
That means that you would be unable to create a child domain called corp.contoso.com because that name was already taken.
It would be helpful to have the IP configuration of all machines involved - address, mask, g/w, DNS. Additionally, the machine name and the structure you are trying to create.

Can I run Windows 8.1 using VirtualBox on my Macbook?

The system requirements for Windows 8.1 says that it needs "Microsoft DirectX 9 graphics device with WDDM driver". Can I run Windows 8.1 using VirtualBox on my Macbook? It's a late 2009 model with an NVIDIA GeForce 9400M 256 MB graphics card & 2 GB of RAM. (Do I need more RAM?)
Thanks!

While I can't answer to the BootCamp specification, I can state the use of Windows and Mac OS X in the MacBook will invite a need to upgrade the RAM; likely to the max it can use. Matching RAM of quality specs so the system will work. The specs are important, as details are everything.
You'd likely use Boot Camp to make a partition on the internal HDD, but then the overall capacity for Mac OS X could be compromised. When you remove a partition, you'd use BootCamp again, or you'd have to erase content in order to restore to original capacity. Disk Utility generally has a harder time with a BootCamp partition.
Good luck & happy computing!

How can I determine what machines have Offline Sync running and are using it

Hi everyone,
I am working on a project where a Windows feature was rolled out but we do not know to whom exactly?
I need to run a script that will tell me for all the machines/PCs in our estates which ones are actually using the Offline Files/Sync Center in Windows 7.
Is there a way to do this via Reporting? I'm actually using SCCM 2012 SP1 but there was no option for this in the drop-down.
If anyone has any samples or scripts - that I could utilise then I would appreciate this.
Thanks

Yes, I know this is an old post, but I’m trying to clean them up. Did you solve this problem, if so what was the solution?
A Quick Bing search revealed several scripts that will allow you to determine offline data. I would start with one of those then, write the results to WMI. Once that is done CM12 can inventory the results and you can then create a report in this data.

Can the boot camp partition be resized once windows is installed and running as virtual machine using vm fusion ware?

I have macbook air partitioned 505/50 and running OSX and win 7 side by side as virtual machines using vm fusion. Can the partition size be changed without starting over?

Very helpful. I started with vm ware to create a pseudo drive but could not import win 7 over home network. mac has no immediate way to connect to network without adapter, and has no cdrom. So i used boot camp to create partition, then made a bootable win7 iso file on a memory stick using win 7 usb/cdrom download tool from microsoft, and rEFIT to get mac to boot from the mem stick into the dos partition. Then i ran vm fusion to import the win 7 partition as a virtual machine. OSx and win 7 run side by side.
Seems from what you say that sizing cannot be accomplished without deleting partition and starting over. If I start over and just run vm fusion to create he win7 virtual machine, not sure how I would bet the minimum win 7 os into the ac. Perhaps vm will boot from the mem stick using refit. Do you know?

How do I run virtual machine on my MacBook Pro running Lion?

I am trying to run virtual machine 7 on my Mac so that I can use windows 7 for some school projects. Whenever I try to run it I ger error messages saying this is not supported. Are there any patches?

Whenever I try to run it I ger error messages saying this is not supported.
When you try to run what? The Windows program?
There are several virtualization options available... Parallels, VMware's Fusion, and VirtualBox. Each of these will require that you have a copy of Windows to install. VirtualBox is free and fully functional. It's not as polished as the other for-pay options, but it's the only one I use. Any one of these utilites creates an environment in which you can install Windows within OS X.

Webcenter Space runs no gui on VirtualBox

Hi all,
After so many tries
I managed to install Web Center Space , on top of PreBuilt VM provided by Oracle using VirtualBox on MacOS , just to get an overview of Web Center.
Since it requires lot of memories, i think i should enable the vm to run with no gui like the SOA Suite Prebuilt VM.
Later , i will access the WebCenter in my Host browser.
Anyone can give me some tips,links to tutorial, would be appreciated, thanks...

hi
may be you are right i tried to change vrdp to rdp and had to change nat to host networking before under the pool settings within vdi
but this expect the virtual machine is connected to host networking instead of nat on the virtualbox cause all clone jobs fails?
if i change the windows template machine on the virtualbox from nat to host interface (network name is greyed out) and select the physical network interface it fails to start the machine
"Failed to open/create the internal network "HostInterfaceNetworking-nge0 Nvicida Gigabit Ethernet - VBox status code: -3700 (VERR_SUPDRV_COMPONENT_NOT_FOUND)
is it true that i have to create a bridge in the virtualbox solaris (not opensolaris) and build scripts which are running during power on / off from virtual machines to solve this issue?

Can 2 gb ram on 2.4GHz run windows 7 using parallell desktop

If I buy the new 13 inches 2.4GHz with 2GB RAM, is it enough to run Windows seven using Parallel Desktop or should I have 4GB of RAM?
Thank you

When running a virtual machine such as Parallel you'd be better off running as much memory in the Book that you can afford. 4GB should be enough but 2GB you may find a little troublesome.
Also look into Sun's "Virual Box" it is a free VM. Not as many bells and whistles as Parallels but work very well.

Should I run losetup when using openfiler for RAC ?

Grid version : 11.2.0.3
Guest OS : Oracle Enterprise Linux 6.3
Host OS : Windows 7 (64-bit )
Hypervisor : Virtual Box 4.2.6
I am planning to set up a 2-node RAC using VirtualBox.
We are going to use OpenFiler as the storage appliance. So, totally 3 VMs (2 RAC Nodes + 1 OpenFiler VM)
Once the LUNs are available , should we be running losetup command ?
losetup /dev/loop1 /disk1as mentioned in
Re: iscsi or SAN
Isn't partition creation using fdisk enough ?
If we use shared LUNs created from withing VirtualBox , should we be running losetup ?

There is insufficient information to provide you with an answer. You are going to need to test your proposed configuration. Hopefully this is just a proof-of-concept or test environment. You have to take leave of all rational thinking to try to use this in a production environment.
You could have probably tested it (installed/tore down/resinstalled) many times over while waiting for an answer.

Running virtual box on different monitors

I have virtual box which I can full screen to create 3 separate desktops. I also have 3 old monitors. What do I need to do in order to get the 3 different desktops on the 3 separate monitors where I can move between them?

Oracle VM is more of an enterprise offering. Not saying that Virtualbox isn't used in the enterprise. It is. Oracle's VDI offering uses Virtualbox. I personally prefer Virutalbox over any of the free host based virtualization offerings out there. Its less intrusive to the host.
Oracle VM supports greater resource allocation and is built to provide enterprise level HA. Yet it requires a greater "footprint" to run. I'd say that Virtualbox is better at the "little things" and Oracle VM is better at the "big things". I have noticed that Virtualbox is a little flacky with 2012 Server virtualization. I've even played around with the new 2012 free Hypervisor offering on Virtualbox and its hit and miss. Crashes more times than not. Not to mention that the new Microsoft 2012 Hypervisor is the biggest convoluted mess I've ever seen. It works okay in a Domain environment but working in a workgroup environment... its about useless. You even have to have a Windows 8 client or a windows 2012 server to load and run the management tools for 2012 Hypervisor. Even when you get them working.... (which like to have drove me crazy)... they really are simplistic to say the least.

Running virtual PC on iMac G3

Hello forum. I'm new at this, so please forgive me if I do something stupid! I have taken over running an annual seminar which has a database that runs in ACT (a PC program). I've been successfully running the database under Virtual PC/OSX on my PowerBook G4, but I want to hand over the running of it to my wife who is running my old iMac G3. I've just discovered I can run Virtual PC under System 9.2 on my old iMac G3 and want to know the best way to do it. My RAM is currently 640MB. I can upgrade this to 1gig can I? My hard drive is only 6GB so I have bought a 160GB Firewire external hard drive from a friend for a song. Instead of installing everything on my poor little internal hard drive, can I install Virtual PC, Windows Software, ACT and my database on the external hard drive and run everything off there? Will it be quick enough to do database updates, emailing, etc. Also my hard drive seems to run slow and I'm wondering if I should copy it across to the external hard drive, erase the internal hard disk and reinstall everything. I have all the original system disks etc. What's the best way to do this if I do? I guess I'm looking for the optimal solution so that I can get the best performance out of Virtual PC on my iMac.
Many thanks for any help in advance!

markafarrelly, Welcome to the discussion area!

Yes
...can I install Virtual PC, Windows Software, ACT and my database on the external hard drive and run everything off there?
Yes
Will it be quick enough to do database updates, emailing, etc.
It will be at least as fast as doing the same thing from the internal drive.
I guess I'm looking for the optimal solution so that I can get the best performance out of Virtual PC on my iMac.
I would either (a) install everything (OS X and everything else) on the external drive and use that as the boot drive, or (b) replace the internal drive with a larger capacity (up to 120 GB) drive and install everything on that.

We have had this issue many, many times before including on the latest 3.6 rev. It appears that when the applicationCache has an update triggered by a new manifest file, the browser may still use only its local network cache to check for updates to the files in the manifest, instead of forcing an HTTP request and revalidating both the browser cache and the applicationCache versions of the cached file (seems there is more than one). I have to assume this is a browser bug, as one should not have to frig with server Cache-Control headers and such to get this to work as expected (and even then it still doesn't sometimes).
The only thing that seems to fix the problem is setting network.http.use-cache to false (default is true) in about:config . This helps my case because we only ever run offline (applicationCache driven) apps in the affected browser (our managed mobile apps platform), but it will otherwise slow down your browser experience considerably.

Having trouble with creation of a cloud service with multiple virtual machines using java sdk.

I am creating a cloud service on azure with 2 virtual machines using java sdk API. Service created successfully.
My input endpoint details are as follows.
INPUT ENDPOINTS
Head : 191.238.144.47:2400
Head : 191.238.144.47:22
Node0 : 191.238.144.47:43211
For Head instance port 2400 is for HTTPS and port 22 is for SSH and for Node0 instance port 43211 is for SSH.
But I am having problem with doing a ssh on Head instance. Sometimes it works sometimes doesn't. Same problem with HTTPS also.
I have some application running over there but when i try to access it thru browser sometimes it works but most of the time doesn't. When I restart the instances from azure portal, its works after
that(not always but most of the time).
Now I am confused what is going on there. I am creating cloud service and virtual machines using java sdk and setting input endpoints also. After creation of all instances i restart every instance programmatically .
I am not sure whether restart is required or not. It must be something to do with input endpoints only but not able to get the right thing i guess. When i do the same thing thru azure portal(creation of cloud service with virtual machines and setting up input
end points) everything works fine but not achieving the result when implementing it by java sdk API. Please help me.

HI Nithin,
Thanks for your reply. I am setting the endpoints after creating my instances using update call. Here's the code snippet.
AzureService aServ = new AzureService(session);
if(aServ.checkNameAvailability(clusterName)) {
aServ.createHostedService(clusterName, "dbX cluster");
// Creating head instance
aServ.createHead(clusterName, imgName, headType, userName, pswd);
// Setting end points for head node
String name = "ssh";
int port = 22;
aServ.updateVMInputEndpoint(clusterName, "Head", name, port);
// Restarting head instance
aServ.restartVM(clusterName, "Head");
String roleName = "Node";
String tmpRoleName = "";
for(int i=0; i<noi; i++) {
port = 43210+(i+1);
tmpRoleName = roleName + i;
// Creating node instance
aServ.createVM(clusterName, tmpRoleName, imgName, nodeType, userName, pswd);
// Setting end points for node instance
aServ.updateVMInputEndpoint(clusterName, tmpRoleName, name, port);
// Restarting node instance
aServ.restartVM(clusterName, tmpRoleName);
// Method to update the input endpoint details
public void updateVMInputEndpoint(String clusterName, String vmName, String name, int port)
throws Exception {
VirtualMachineGetResponse resp = computeManagementClient.getVirtualMachinesOperations().
get(clusterName, clusterName, vmName);
VirtualMachineUpdateParameters updateParameters = new VirtualMachineUpdateParameters();
//get the configuration list
ArrayList<ConfigurationSet> configlist = resp.getConfigurationSets();
//get inputendpoint list and update it
ArrayList<InputEndpoint> endpointlist = configlist.get(0).getInputEndpoints();
InputEndpoint inputEndpoint = new InputEndpoint();
inputEndpoint.setEnableDirectServerReturn(false);
inputEndpoint.setPort(port);
inputEndpoint.setLocalPort(port);
inputEndpoint.setName(name);
inputEndpoint.setProtocol(InputEndpointTransportProtocol.TCP);
endpointlist.add(inputEndpoint);
// Open port for https on head node
if(vmName.equals("Head")) {
inputEndpoint = new InputEndpoint();
inputEndpoint.setEnableDirectServerReturn(false);
inputEndpoint.setPort(2400);
inputEndpoint.setLocalPort(2400);
inputEndpoint.setName("https");
inputEndpoint.setProtocol(InputEndpointTransportProtocol.TCP);
endpointlist.add(inputEndpoint);
updateParameters.setConfigurationSets(configlist);
//required for update
OSVirtualHardDisk osVirtualHardDisk = resp.getOSVirtualHardDisk();
updateParameters.setOSVirtualHardDisk(osVirtualHardDisk);
updateParameters.setRoleName(resp.getRoleName());
OperationResponse updtResp = computeManagementClient.getVirtualMachinesOperations().update(clusterName, clusterName, resp.getRoleName(), updateParameters);
And every time i am creating a new cloud service along with head and node instances. Region is "South Central US".
I am setting ProvisionGuestAgent field to true at instance creation time. Thank you.

CFMX 6.1's Virtual Memory Use problem!!

I appologise for the long post in advance...
Ok... so I have this script that, using cfdirectory, will
check a directory for any files that may have been uploaded, if
there are files, it loops through the results and reads the files
one at a time, line by line, using the FileReader.cfc (Uses the
Java FileInputStream, InputStreamReader, and BufferedReader to
provide a way to incrementally read large files). The files are
just pipe "|" delimited data, each line represents a record for a
db table.
Now as it's reading each line, it will perform some basic
string parsing to clean up the file line to make sure the data is
valid, blah blah blah and then it will write that "cleaned" line to
another file using FileWriter.cfc (Java component once again). Once
it's completely done reading the original file, it will close it
and it will open the new "cleaned" version of the file, read it
(FileReader.cfc), create an INSERT statement and then update the
database table.
Now... this all works GREAT... until it has to loop through
more than a few files... 3 - 4 files are NO problem! works like a
charm, but throw 6 - 8 files at it and it dies, not a timeout mind
you but an actual "java.lang.OutOfMemoryError" (now, I've tried
making all the files exactly the same (just changed the name) and
the weird thing is, it takes longer and longer to process each as
it goes through the loop... I have the script write some stats as
it's looping:
FILE 1 STATS
Name: COA0607_Intranet1.DAT
Status: Import Successfull
Line Count: 32,971
Processing Time: 74,237ms
FILE 2 STATS
Name: COA0607_Intranet2.DAT
Status: Import Successfull
Line Count: 32,971
Processing Time: 82,018ms
FILE 3 STATS
Name: COA0607_Intranet3.DAT
Status: Import Successfull
Line Count: 32,971
Processing Time: 94,476ms
FILE 4 STATS
Name: COA0607_Intranet4.DAT
Status: Import Successfull
Line Count: 32,971
Processing Time: 145,108ms
I know what you guy are probably thinking; "Woah man... CF
isn't really meant to do that kind of processing...", I know, trust
me I know... however, I really neeeeeed it too lol.
Ok, so as the script is running, I watch the Virtual Memory
use of jrun.exe, processing say 3 - 4 of these files brings up the
usage to approx 300,000k which yes, is a LOT but that's fine...
this process is meant to run at night via a Scheduled Task...
When I run more than 4 files, things start to get ugly, keep
in mind that these are EXACTLY the same files just re-named
differently. The script will start lagging BIG time and on the last
file (usually the last file) I'll see the memory usage spike from
350,000K all the way up to 600,000K and that's when it throws the
"java.lang.OutOfMemoryError" and dies... I've tried commenting out
the part of the script that updates the db, but still get the same
problem...
So... what gives? How come CF Server does this??? I mean, it
runs fine for the first few files... and then WAM, it dies... sorry
for the long post... any insight here is VERY much appreciated...
it would be AWESOME if the wonderful folks at Adobe could shed some
light on this for me : )

Looks like it is "incremental" only in the sense that it increments

Well I did try cffile originally... and it didn't even run...
