I have ubuntu 18.04 server in which i have installed below packages to setup kvm:
qemu-kvm libvirt-bin bridge-utils virtinst virt-manager
Virt-manager is failing to open with below error:
Unable to init server: Could not connect: Connection refused
Unable to init server: Could not connect: Connection refused
Unable to init server: Could not connect: Connection refused
**(virt-manager:3026): Gtk-WARNING : 14:09:54.999: cannot open display:
I have logged into server with -X option and in my sshd_config file, X11Forwarding is yes.
libvirtd service is active and running.
Output of kvm-ok command is:
INFO: /dev/kvm exists
KVM acceleration can be used
Can someone help me fix it?

I am trying to install SQL Server on M1 based Mac with Docker.
https://debugsolutions.wordpress.com/2021/03/17/using-sql-server-on-m1-based-mac-with-docker/
Made it all the way to end of step 5, but my container won't connect. I am getting:

How can I fix this?
The command I ran at end of step 5:
docker run --cap-add SYS_PTRACE -e ‘ACCEPT_EULA=1’
-e ‘MSSQL_SA_PASSWORD=Password.1’ -p 1433:1433 --name azuresqledge
-d mcr.microsoft.com/azure-sql-edge
` replace ' in docker command
$ docker run --cap-add SYS_PTRACE -e 'ACCEPT_EULA=1' -e 'MSSQL_SA_PASSWORD=Password.1' -p 1433:1433 --name azuresqledge -d mcr.microsoft.com/azure-sql-edge
A bit late to the party but if you don't want to resort to using the cutdown Edge edition I found away to get SQL Server Linux going using an open source tool called Lima and Rosetta as the VM: https://dev.to/srburnham/forget-azure-sql-edge-on-a-m1-mac-run-full-blown-sql-server-linux-instead-a-how-to-6d2
After trying several approaches such as this one on Mac and I still get the error below when I do gcloud app deploy. I also tried manually adding the freetds driver to ODBC Manager GUI but once I cick 'Ok' it doesn't show in the list of drivers. Same thing happends for the DSN for both user and system. I would greatly appreciate any help.
Step 6/14 : ADD odbcinst.ini /etc/odbcinst.ini

I am using Docker to install SQL Server on Mac OS. But i have an error Error: Failed to connect to localhost:1433 - connect ECONNREFUSED 127.0.0.1:1433. I have set memory to 6GB, password is strong enough but it still not works.
I got the same issue when I've tried to connect Azure Data Studio to the container,
I used the command lsof -nP +c 15 | grep LISTEN
turns out that it listen on port 1401
So I wrote that in the field of the server "localhost, 1401"
and it works,
There is another solution,
which is in the docker PREFERENCES and its about the memory you have to give it at least 3.25 GB so that the SQL Server runs.
I deployed a Cassandra cluster through their launcher: https://cloud.google.com/launcher/explore?q=cassandra
I can connect to the VM fine, through SSH/PuTTY.
Then when I try to connect with for example DBeaver I get:
com.datastax.driver.core.exceptions.NoHostAvailableExeption: All host(s) tried for query failed(tried: /x.x.x.x:9160)
com.datastax.driver.core.ConnectionExption:[/x.x.x.x:9160] Unexpected error during transport initialization. Connection has been closed
Or with cassandra-driver (nodejs), I get:
All host(s) tried for query failed. First host tried, x.x.x.x:9160: Error: read ECONNRESET. See innerErrors.
InnerErrors: { 'x.x.x.x:9160': { [Error: read ECONNRESET] code: 'ECONNRESET', errno: 'ECONNRESET', syscall: 'read' } }
Info: Represents an error when a query cannot be performed because no host is available or could be reached by the driver.
I've forwarded the 9160 port in the google developer console and it seems to work because when I stop the cassandra server on the VM it gives a different error, indicating connection is refused:
All host(s) tried for query failed. First host tried, x.x.x.x:9160: Error: connect ECONNREFUSED. See innerErrors.
InnerErrors: { 'x.x.x.x:9160':
{ [Error: connect ECONNREFUSED]
code: 'ECONNREFUSED',
errno: 'ECONNREFUSED',
syscall: 'connect' } }
Info: Represents an error when a query cannot be performed because no host is available or could be reached by the driver.
Now, I've tried editing the cassandra.yaml rcp_adress to the actual external address instead of 0.0.0.0.
I've also tried the internal serverfarm address.
I've not changed the default authentication (but also tried with auth):
authenticator: AllowAllAuthenticator
# authenticator: PasswordAuthenticator
authorizer: AllowAllAuthorizer
# authorizer: CassandraAuthorizer
I'm at a loss, the connection seems to work, but cassandra seems to not allow a login or reset the connection?
You are trying to connect on the thrift port (9160). You should be using the native protocol port (9042).
I am new to mongoDB and i am trying to get it configured and running on my Ubuntu server. When i go and enter this command in my terminal
sudo service mongod start
I get the following output
start: Job is already running: mongod
So, when i try to enter the shell with
mongo
I get the following output
2015-02-24T14:54:39.557-0800 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2015-02-24T14:54:39.559-0800 Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146
I know I'm not working locally so I heard over to the mongod.conf file and change the following
port = 5000
# Listen to local interface only. Comment out to listen on all interfaces.
bind_ip = 10.0.1.51
Where bind_ip is now my ubuntu server and the port is 5000 as shown, so now i restart the service with
sudo service mongod restart
and outsputs
mongod start/running, process 1755
And now I try to renter back into shell with
mongo
and i still get the same error messages
MongoDB shell version: 2.6.7
connecting to: test
2015-02-24T15:01:26.229-0800 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused

exception: connect failed
Can someone help me out with this issue? I've been going through the forums and nothing appears to be working. Thanks.
If anyone is having trouble, i looked into mongod --help and found the following solutions
mongod --smallfiles
or
mongod --nojournal
hope this helps anyone.
