Steps to Reproduce Bug:
Start emulator with "-timezone" parameter(e.g emulator -avd Pixel_5_API_33 -timezone Asia/Shanghai)
Issue is reproducible when API level of the emulator is set to 31+. When API level is 30 emulator works as expected

Expected Behavior:
Emulator starts with timezone set to provided parameter value

Observed Behavior:
Emulator ignores the parameter and starts with host devices timezone.

please run emulator with the following options and post the output here, thanks!
/path/to/emulator -verbose -show-kernel -avd <avename> -feature -ModemSimulator

the above command line will not use modem, just to see if it is related.

Yes,it worked.

Attaching the log below.

I'm getting the same error on my Ryzen 1800X on OpenSUSE Tumbleweed:

"qemu-system-x86_64: -chardev socket,port=38379,host=::1,nowait,nodelay,ipv6,id=modem: address resolution failed for ::1:38379: Name or service not known"

Adding the "-feature -ModemSimulator" flags worked around the issue for me.

Hi truefalsetrue101@, could you try look at your /etc/hosts file on your machine? On my machine, it looks like

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1	localhost
255.255.255.255	broadcasthost
::1             localhost

If ::1 localhost is missing, that probably explains why "Name or service was not known".

ta...@gmail.com <ta...@gmail.com> #7Jan 23, 2023 01:51AM

I have that entry. Here's my entire /etc/hosts (my IP and hostname have been replaced with "xxx"):

#
# hosts         This file describes a number of hostname-to-address
#               mappings for the TCP/IP subsystem.  It is mostly
#               used at boot time, when no name servers are running.
#               On small systems, this file can be used instead of a
#               "named" name server.
# Syntax:
#    
# IP-Address  Full-Qualified-Hostname  Short-Hostname
#

127.0.0.1       localhost

# special IPv6 addresses

RE#7

bohu@, any idea why this call would fail on host? I am also guessing maybe it has to do with the /etc/resolv.conf on host.

    if ((rc = getaddrinfo(addr, port, &ai, &local)) != 0) {
        error_setg(errp, "address resolution failed for %s:%s: %s", addr, port,
                   gai_strerror(rc));
        goto err;
    }

"I'm getting the same error on my Ryzen 1800X on OpenSUSE Tumbleweed"

could be related to the linux flavor regarding address resolution.
my machine has almost the same config, and the getaddrinfo just works.
I wonder if there is some sys log you can put up here regarding that error.

It seems linux hosts have lots of problem regarding this, might be better use different ways to hook up the modem.

[Deleted User] <[Deleted User]> #11May 15, 2024 12:30AM

OpenSUSE Tumbleweed has a toggle in it's network settings for "Enable IPv6". I don't have IPv6 on my internet connection and none of my local devices need it, so I usually leave it disabled.

I tried enabling it and viola, the emulator is starting for me again (without needing the ModemSimulator flag).

It looks like that toggle adds net.ipv6.conf.all.disable_ipv6 = 1 to /etc/sysctl.conf.
