Error: The largest virtual memory that can be allocated is 0 MB

Hi !
When I try to create virtual machine in my VM Manager I get this error when I supply corresponding memory size.
How can I soilve this?
Thanks...

Hi
Did you get a solution to your issue?
I cannot migrate any VM's onto one of my servers as I get a OVM-4021 Not enough memory for migration error.
When I do a xm info | grep memory, I get the following
xm info | grep memory
total_memory : 8186
free_memory : 7517
node_to_memory : node0:7517
Yet - from the cluster master, if I run a /opt/ovs-agent-2.3/db/db_dump.py srv, I get the following for the same server
{'cpu_idle': 0.98999999999999999, 'cpu_num': 4, 'ip': '10.30.32.62', 'agt_username': 'oracle', 'real_status': 'ALIVE', 'mem_total': 8186, 'cpu_speed': 3991.9699999999998, 'agt_passwd': 'PASSWORD', 'hostname': 'rrsyd112', 'agt_url': 'https://oracle:PASSWORD@rrsyd112:8899', 'master_weight': 0, 'vcaps': 'xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64', 'agt_port': 8899, 'status': 'RUNNING', 'cpu_avail': 15808.2012, 'arch': '64bit', 'is_shared': True, 'mem_free': 0, 'shutdown_mode': False, 'agt_addr': 'rrsyd112', 'srv_role': 'utility,xen', 'agent_version': (2, 3, 0, 19)}
My problem is that ovs-agent shows mem_free of 0 - when in fact xen reports free memory of 7517.
Thanks
George

OVM-4006 The largest virtual disk that can be allocated is 78,027 MB

G'Day List,
Greetings and best wishes.
I am hoping someone will be able to help me here:
PROBLEM:
I tried to "Create New Virtial Disk" for a particuler VM and it error out as shown in the subject line.
Figuring that it was a space issue, I stopped another VM with a 800GB D drive - Deleted the 800GB
drive and attempted to "Create New Virtual Disk" of only 580GB and got the same error.
I do not believe it has to do with the SAN so I am looking for an OVM reason for the error and a solution.
Anyone?
Thanks
Ferg

Hi,
When you say - deleted 800 Gb drive does that mean taht you deleted the storage space for that virtual machine , or completely deleted the machne from amanger
If you have 2.2 version for OVM server - it displays the info about max memory and max disk space available to use .
If you are getting space related error make sure that you delete the stuff from the server and not the entry only from the manager database.
Try selecting a VM which you want or plan to delete to free up the space
Go to 'Actions' Menu and select delete
next page - Check " Remove image files from storage"
And hit "delete"
This will remove the entry from the server as well and free up the space.
you can also login to the server and do "# df -h" .This will also show you how much sapce is really available on the disk .

What is the largest hard drive that can be put in a Macbook Pro 17 MA897

I am looking to upgrade an existing Macbook Pro 17 model MA897 and am looking for the specifications as to the largest hard drive that can be installed and where is the best place to purchase drives.

The HDD makers have yet to breach the 1TB limit in the 2.5" formfactor. But there is hope, as one of the makers (Toshiba, IIRC) announced the discovery of a radical new way of magnetic encoding which will permit much denser packing of the magnetic domains in the rotating disk, and much higher capacities. Promised to come out with 3-4TB 2.5" devices before the year is out and maybe 10TB+ in the coming years. We'll have to wait and see.
BTW and since The Age of the Lion (and probably Mountain Lion too) has forsaken the need of an optical drive for system recovery, some users have decided to remove the no longer critical device and planting another HDD in its place. Might be looking into if you really need the capacity and don't care to lug even more weight above of what the 17" entails.

Max data segment that can be allocated per process

What is the maximum data segment that can be allocated per process on solaris?
(The equivalent of "maxdsiz" on hp-ux).
Thank you,
J

its configurable. Look at the rlimit max for the process. There should also be defined a maximum value you can set the rlimit to somewhere in the sys/* headers. (sorry can't track it down, my dev machine is kaput).

In the past I have always been able to adjust the memory of each individual application,
my Adobe Illustrator CS5 appears that is doesn't have enough memory to complete a particular project.
How do I boost the amount of memory that Illustrator uses so I can complete my project?

With OS X, it automatically allocates RAM and it can't be allocated manually.
What model Mac do you have and what OS X version is it running. Your profile shows a PowerMac and OS 10.6.8. A PowerMac can't run OS 10.6.8. It's max OS is 10.5.x
How much RAM is installed in your Mac? You need to max out the RAM and close other open apps if you are having problems with Illustrator.

HT4059 What is the largest iBook size I can author?

I am makeing my first iBook using Pages for my text. The book is just for my family and not for publication. What is the maximum size that I can convert to an iBook?

The largest capacity HDD that you can install is the HGST 1.5 TB HDD:

Any 2.5" 9.5mm thick SATA HDD will fit and operate in your MBP, regardless of capacity.

What is the largest hard drive I can upgrade to for MacBook Pro A1278 Early '11

What is the largest hard drive I can upgrade to for macbook pro A1278 Early 2011? I have seen 750GB on some websites, but I would like a 1TB I am looking for SATA 6.0GB, 1TB 7200. Is this dependant on the physical size of the hard drive? I have seen a height of 15mm and 9.5 mm. How do I know what will fit??

I have not seen any 7200 rpm 1 TB HDDs. They all are 5400 rpm. I would say that this HDD comes closest to your requirements. Tomorrow, there may be others.

When I sync my iphone 4S using iTunes it only syncs 8.5GB of music, not the entore library as specified. Is there a capcity default limit of the amount of storage that can be used for music and if so how do I change it?

The only limit is that of the device. No restrictions on how much of it you can use for music. Is part of your music library unchecked?

How do I delete excess email messages from my iPhone. There are 300 messages listed, and every time I delete some, more are added from old messages. How do I limit the number of messages that can appear on my phone? How can I delete messages in bulk,

You can't.
All photos transferred from your computer are stored in the Photo Library. The photos in the album or albums below are not duplicates - they include a pointer to the original photos stored in the Photo Library. This way you can view the photos in a particular album only by selecting the album, or you can view all photos available in all albums by selecting Photo Library.
Just as with an iTunes playlist. A song cannot be in an iTunes playlist unless the song is in the main iTunes library. Placing a song in a playlist does not duplicate the song. Remove the main iTunes library or the songs from the main iTunes library that are in a playlist and the songs will no longer be in the playlist either. This way you can listen to the songs in the playlist only by selecting the playlist, or all songs in your entire iTunes library by selecting Music under Library in the iTunes source list.
The same with iPhoto on a Mac. A photo cannot be in an in iPhoto Event or Album unless the photo is in the main iPhoto library. Placing a photo in an Event or Album does not duplicate the photo. This way you can view the photos in an iPhoto Event or Album only by selecting the Event or Album, or all photos in all Events or Albums.

How can i set the number of results that can be displayed on the page

hello im just wondering how i can set the numebr of results that can be dispaleyd on the jsp, when the there are more than 5 results i want the suer to press more
how is this odne could anyone send me a example code?
and also how can i get results from the query displayed as select list options, so that when they press one of teh results it goes to correspnding page
Thank you

Hi,
I assume that you have the connection to the DB.
You can try this code.
Statement stmt = con.createStatement();
String sql = "<some sql code for selecting>";
ResultSet rs = stmt.executeQuery(sql);
rs.last();
int count = rs.getRow(); // this is the number that shows how many numbers you have after select query
rs.first(); //we moved cursor again to the begining of the results.
if (count > 5) {
for (int i=0;i<5;i++) {
//as an example
rs.getString(0);
rs.getString(1);
rs.getString(2);
out.print("<a href='morePage.jsp'>More</a>");
else {
for (int i=0;i<count;i++){
//as an example
rs.getString(0);
rs.getString(1);
rs.getString(2);
rs.close();
stmt.close();I hope this would help you.
If you have problems let me know..
