Virtual Machine Manager, when I start the Ubuntu VM got the boot error as
'Boot from (hd0,0) ext4 daecfb55-8eef-4a7a-b958-f9c3db33e2ff starting up..'
as per in the screenshot boot error
This doesn't seem like an error. It's just a message from your bootloader telling you where it's booting from. Ensure your machine has enough resources to boot. Underpowered virtual machines boot very slowly.

I have Redhat 6.10 Synchronizer Server and xen client device setup. I am able to download updates via a manager software which run on xen client device.
But each time I want to download the update.tar
I restart the apache and then client xen device.
or I have to reboot the xen client device which I want to update then it downloads.
But sometimes even on xen client device reboot the update.tar wont download.
xen-client: downloading ....and it just keeps downloading without downloading it. It times out. I believe that for the update to download on the xen client device just restarting the xen client or invoking the client service should be enough. There should be no need to restart apache and then restart the xen-vm-client.
I am not able to download without restarting the httpd server. ie I have to run 'service httpd restart' and then immediately 'xen-vm-client reboot' . But without this I am not able to download the update.tar by just firing 'xen-vm-client reboot' on Xen. I have to restart httpd and then xen client device for it to download.
I had an issue with Redhat 6.10. After 'yum install httpd' and rebooting redhat it wont boot up. And then after debugging through the boot process, I figure out that httpd service running at different runlevels on boot stops redhat from booting up. So had to
chkconfig httpd off
chkconfig httpd --del
This fixed the issue of httpd at runlevels hanging the redhat bootup. But I think this could be the reason why I have to restart httpd to get the update to download. Otherwise if I reboot the xen client device it downloads without a httpd restart. So any hints/ideas are really appreciated.
Please give me some understanding about why this is happening and how this can be solved if you know.
Once again grateful for all the help.

Next what I ll try is 'chkconfig httpd on' this might again cause the redhat to hangup on booting. And thus I may have to reinstall the entire Synchronizer redhat 6.10 setup. Or still trying to investigate about the issue.
I am trying to deploy a cent-os 7 VM on a vcenetr from pyvmomi python library and then before powering on the VM I am trying to setup static IP and DNS for the VM.
VM creation goes fine , but guest customization fails, givimg following error:
**Customization of the guest operating system 'rhel6_64Guest' is not sup
ported in this configuration. Microsoft Vista (TM) and Linux guests with Logical
Volume Manager are supported only for recent ESX host and VMware Tools versions
. Refer to vCenter documentation for supported configurations."
faultCause =
faultMessage = (vmodl.LocalizableMessage) []
uncustomizableGuestOS = 'rhel6_64Guest'
Now this customization problem goes away if the VM is just rebooted once. After that we can do the guest customization.
But this reboot takes around 30 seconds of time and for our case , we need to get VMs up and running faster than this time.
Any body who faces similar problem and has some context on it will be very helpful.
Also I don't understand how rebooting the VM solves this problem.
Please share your thoughts even if you don't have exact solutions .
On further Investigation I found that open-vm-tools does not work until the VM is powered on atleast once.
When Machine is powered on , the HOST system detects the open-vm-tools running on guest OS , and from there on open-vm-tools works.
So open-vm-tools can not be used for initial provisioning as it will just not work at the start up.
Cloud-init is the alternative solution which should be used for initial provisioning.
I am using Ubuntu 14.04 on VmWare-Player 10. My host system is Windows 7. It worked fine, but since I restarted my host system (I have done this often and it was working without any problems) it stucks at the ubuntu boot up:
I have restarted my host system and it locked again:
Do I have to change something in the log files or how can I fix this?
Thanks in advance,

I use Virtual Machine Manager to run several Guest OSs with QEMU-KVM. I read it somewhere that by inputting ctrl+alt+2 should pop up monitor console. It is not working or disabled. Is there any way I can turn it on?
What I am trying to do is to dump physical memory of GuestOS.
With this command,
pmemsave 0 0x20000000 /tmp/dumpfile
If you use Virtual Machine Manager, you most likely also have "virsh" tools installed. You can use it to transmit qemu-monitor commands to your VM:
virsh# qemu-monitor-command vm-name --hmp "pmemsave 0 0x20000000 /tmp/dumpfile"
I run Debian linux.
I want to make a virtual machine in virtualbox, wich boots from a server via drbl.
The server will be my laptop.
The virtual machine start booting, but fall into infifite boot-loop.
It load one part of the OS from the server, then stop loading, start it again...
Have anyone seen this error?
