Does anyone know which package provides virt-install CLI tool in Yocto or how to use virt-install tool in yocto environment?
I have added below packages in my bb file but I don't see virt-install tool getting built
packagegroup-core-boot \
qemu \
libvirt \
libvirt-libvirtd \
libvirt-virsh \
libvirt-python \
kernel-module-kvm \
kernel-module-kvm-intel \
kernel-module-kvm-amd \
Please help me.
Not 100% sure about Yocto, but I think virt-manager usually provides virt-install.

I tried various methods explained on internet, but none seems to be working. using local iso image give one issue and location gives another issue.
Can we setup IP using this command?
currently using this command
sudo virt-install \ --name worker-2 \ --ram=4096 \ --disk size=100 \ --disk path=/opt/sciserver/vm/worker-2.qcow2,size=30,format=qcow2 \ --vcpus 2 \ --os-type linux \ --os-variant ubuntu20.04 \ --graphics none \ --location 'http://archive.ubuntu.com/ubuntu/dists/focal/main/installer-amd64/' \ --extra-args "console=tty0 console=ttyS0,115200n8"
and error says..
"ERROR Error validating install location: Could not find an installable distribution at 'http://archive.ubuntu.com/ubuntu/dists/focal/main/installer-amd64/'
The location must be the root directory of an install tree.
See virt-install man page for various distro examples."
Your help will be much appreciated
I'm compiling a software (to convert ASCII to BIN) in LINUX, using PGI 2019 community version.
The Makefile use pgf77 which not included in the PGI compiler I have in my system, so I have to change to pgf90. However, I faced to an error:
pgf90 -vms -c -O -Mbyteswapio simcon.f
pgf90-Error-Unknown switch: -vms
make: *** [simcon.o] Error 1
I think the -vms is not recognized by pgf90. So what flag should I use here instead?
The MAKEFILE like this:
FCFLGS = -O -Mbyteswapio
OBJCTS = \
aircon.o \
airconv.o \
avgcon.o \
avgcns.o \
bndcon.o \
checon.o \
dfbcon.o \
emicon.o \
metcon.o \
ptscon.o \
regcon.o \
simcon.o \
tercon.o \
tmpcon.o \
tmpcn3.o \
tpccon.o \
wndcon.o
airconv: $(OBJCTS)
pgf77 -o airconv $(FCFLGS) $(OBJCTS)
.f.o:
pgf77 -c $(FCFLGS) $<
simcon.o: simcon.f
pgf77 -vms -c $(FCFLGS) simcon.f
Thank you very much.

pgf77 was in the process of being deprecated with the PGI 2019 compilers. It's still there, but only included under the older non-LLVM versions of compilers (i.e. "$PGI/linux86-64-nollvm/19.xx/bin" directory). Though it would be best to move to the newer pgfortran driver (pgf90 works as well).
The "-vms" flag enabled very old VAX/VMS extensions that have been superseded by Fortran standard routines or other extensions. As you note, the code compiles without the flag, so either the code doesn't actually use these extensions or it can use the 3F version of the extensions.
I'm trying to start tensorflow-serving with the following two options like on the documentation
docker run -t --rm -p 8501:8501 \
-v "$(pwd)/models/:/models/" tensorflow/serving \
--model_config_file=/models/models.config \
--model_config_file_poll_wait_seconds=60
The container does not start because it does not recognize the argument --model_config_file_poll_wait_seconds.
unknown argument: --model_config_file_poll_wait_seconds=60
usage: tensorflow_model_server
I'm on the latest docker image, 1.14.0 and the line is taken straight from the documentation
https://www.tensorflow.org/tfx/serving/serving_config
Does this argument even work?
Many thanks.
It seems https://www.tensorflow.org/tfx/serving/serving_config is talking about code that has not been released as a new version yet, which is odd. I will ask about that.
That package is generated from this source:
https://github.com/tensorflow/serving/blob/master/tensorflow_serving/g3doc/serving_config.md, it mentions the --model_config_file_poll_wait_seconds flag.
However, the same document for 1.14.0 has no mention of the flag:
https://github.com/tensorflow/serving/blob/1.14.0/tensorflow_serving/g3doc/serving_config.md
Try using the nightly tensorflow serving image and see if it works.
docker run -t --rm -p 8501:8501 \
-v "$(pwd)/models/:/models/" tensorflow/serving:nightly \
--model_config_file=/models/models.config \
--model_config_file_poll_wait_seconds=60
Just tried. Tensorflow Serving 2.1.0 supports it while 1.14.0 doesn't.
Can someone tell me how to enable the VNC in VM which is being created using virt-install on KVM hypervisor?
My server doesn't have a GUI so I used to run the following command to spin up a VM:
virt-install \
--name centos6 \
--ram 1024 \
--disk path=/var/lib/libvirt/images/centos6.img,bus=virtio,size=30 \
--vcpus 1 \
--os-type linux \
--os-variant rhel6 \
--network bridge=br0 \
--graphics none \
--location 'http://mirror.i3d.net/pub/centos/6/os/x86_64/' \
--extra-args 'console=ttyS0,115200n8 serial'
Now I want to install GUI on the VM(centos6) and install VNC, can someone tell me how to achieve that?
Thanks.
Found answer on this link though it is implemented on ubuntu but same can be replicated for other distribution : https://www.howtoforge.com/tutorial/ubuntu-gnome-vnc-headless-server
I'm trying to compile the ffmpeg library for iOS5. I tried different options but none works.
I downloaded this: https://github.com/ciphor/ffmpeg4ios .
I tried the original build_armv7 but it didn't work. I edited the build_arm7 file and now it looks like this:

rm armv7/*.a

But i get this error:

I looked all over the Internet. I have read all the posts on stackoverflow about this but none helped me. Please tell me what i'm doing wrong and please don't post me links: trust me, i saw them all!
That worked for me with iOS 5.0 and Snow Leopard.
You have to change ldflags, sysroot and cc to provide valid paths to files in Mountain Lion

Inspect config.log file in your root compilation directory and search for "C compiler test failed.`' You will find right there the command that was tried and the exact reason why it failed (i.e., the compiler output).
It could be that the compiler installation directory is not /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/, or that some library cannot be found, etc...
Actually, what I see is that you are specifying on the configure command line a few paths. Have you checked that they are correct for your Xcode version?
If you require ffmpeg 11
You may need to use snow leopard or lion, Mountain lion seems to be missing critical gcc compiler components. We are looking into fixing our build scripts for this
If version isn't all that important to you, we have a pre-built framework for ffmpeg 8, really
we don't find any great difference between using the two and find that ffmpeg 8 has less performance issues.
https://github.com/mooncatventures-group/ffmpegDecoder
If you have a build box with lion or snow leopard you can probably modify our build script and build ffmpeg 11 , others have done this.
