This cause me a big production problems, please help me.
one virtual machine shutted down unexpectly.
The Hype-v log shows:
DM operation add for the virtual machine 'XXXXName' failed with error: Unspecified error (0x80004005) (Virtual machine ID 7EDDD39A-F963-4FAA-8854-6179B7611AC3).
could it be possible if nobody touch the Hype-v and DM error happened??? please tell me how to fix this problem.
DM is "dynamic memory". Your virtual machine tried to add memory and failed. A human didn't trigger this, you've just run out of memory.

Edit: the reason it failed, the error code, is explained here. It's possible there was a permission problem trying to allocate more memory. But still, essentially, you ran out of memory.

the VM does not start and I get this error.
I also tried to resize the VM, but the problem is not solved.
Error: Allocation failed. The available capacity is not sufficient for the virtual machine size required in this area.
any idea??
my client can't work
A few weeks ago i set up my system using Fedora 31 and Cockpit and KVM/libvirt/qemu as host for my virtual machines.
I have 8 virtual machines at all, one for every service, but only one is not doing it's job.
There is one virtual machine, using Debian 10 and ZFS, and it was doing it's job really well, until it's first reboot.
After the reboot it's getting stucked. So what did i do? I have set up a new Debian 10 system, installing ZFS again, rebooting to get the kernel module zfs running, and another reboot --> System get's stucked after receiving "Welcome to GRUB!" message.
Any other virtual machine is running fine, but when i try to create one with nothing else installed, just ZFS it's having issues.
What's the problem, and does someone have some ideas?
First i'll proceed with using Debian 9, and disabling any updates, maybe there is some problem.
Here i got some log, i received by libvirtd.service when this happens.
internal error: End of file from qemu monitor

I've read numerous posts about Semaphore issues, but none appear to be related to this particular issue. I am running Apache 2.4 and PHP 7.1 as part of Zend Server CE, and when starting the Apache service, the following fatal error shows up in the Apache error log:
ZShmStorage(): Fatal error: failed to allocate semaphore. Permission denied
I'm guessing that is related to shared memory storage, but I'm unclear ...
what it is actually trying to allocate the semaphore for
where to look for configuration relating to said semaphore
I thought maybe it was related to the Zend Cache, so I made sure that the permissions looked correct for the [ZendServerPath]/tmp/datacache.
I also thought maybe it was related to the PHP Sessions, so I made sure that the directory specified for the session.save_path in the [ZendServerPath]/etc/php.ini file had proper permissions as well.
I'm unsure where else to look, as there doesn't appear to be any discussions (that I've found) relating to this, but instead it's all about available space and whatnot. In the off chance that it was related to something that borked during allocation, I went ahead executed ipcs -s and noted that there were ~20 Semaphore Arrays present while the Zend Server was running. I stopped the service and ran ipcs -s again -- no Semaphore Arrays were left lingering. Restarted the Zend Server service and the error was encountered again and ~20 Semaphore Arrays were also reallocated.
Any assistance or info to point me in the right direction would be appreciated.
I know this is too late to help #amorio, but maybe it'll help someone else.
The error is specifically from ZShmStorage(), which means it's not apache or php's fault. It really doesn't help that the error message is a bit misleading.
A bit more context on the error, at least in my case. I'm betting it's the same using php(-cgi).
Starting php-fpm (/usr/local/zend/sbin/php-fpm --nodaemonize -c /usr/local/zend/etc/php-7.1-fpm.ini --pid /usr/local/zend/var/run/php-fpm.pid --fpm-config /usr/local/zend/etc/php-7.1-fpm.conf) [10.11.2020 18:18:05 ERROR] ZShmStorage(): Fatal error: failed to allocate semaphore. Permission denied

<b>Warning</b>: Could not initialize Zend Data Cache: Fatal error: failed to allocate semaphore. Permission denied in <b>Unknown</b> on line <b>0</b><br />
Zend Server installed to /usr/local/zend.
I ran into this same issue on ZendServer 9.1.10 on Ubuntu 16.04. In my case, I had to fix permissions on /usr/local/zend/tmp/datacache so www-data (apache user) had write access.
/usr/local/zend/etc/conf.d/datacache.ini is where the save path is defined.
I have a program in Apache + Delphi XE7 with Datasnap. My httpd.exe of Apache consume memory until give messsage "Out of Memory" then I need to restart it.
I developed a simple program just testing this problem. In this program I ve configured Server Module (FD components, Mysql) and WebModule appropriately
In client I have a DBGrid that shows the content of a query.
I open TaskManager and monitor the memory.
The problems:
if I connect and disconnect TSQLConnection the memory increase.
If I open and Close TClientDataSet the memory increase.
What I have already did:
I used Pascal Analyzer searching memory leaks but it´s all fine
I couldn't use ReportMemoryLeaksOnShutdown in the server, because is a DLL, and I dont know how to do this :(
I tried to turn off keep alive of Apache but there is no difference
I ve tried all types of LifeCycle in WebModule (Session, Server and Invocation) no difference too.
Anyone has a problem like this? work with this softwares? And could help?
Tks
I have packstack-allinone setup on my RHEL7.1 trial for Juno release.
I am facing problem while launching VM(for ex: cirros) with a disk size mentioned in flavor. If there is 0gb disk size then VM are getting launched but not for higher flavor sizes.
I also observe that when I do this, openstack-nova-compute service goes down which I observed when I checked using nova-manage service list with nova-compute being XXX making me restart the service everytime I try this scenario. The compute logs doesn't throw any error, it just gets stuck at "Creating image".
Is there any Filesystem issue which i missing to be configured? I am new to this, so please help.
PS: I run all commands with "root" user.
The problem was with esxi. Esxi needs to be 5.5v to support RHEL7x Since mine was 5.1v it only supported RHEL6x.
After upgrading esxi5.1 to 5.5v it worked fine.
