我有在BIOS中启用VT的Dell OPTIPLEX 755计算机,但是当我试图使用KVM检查时,我会得到以下错误
我漏掉了什么?
root@nova-controller:~# kvm-ok
INFO: /dev/kvm does not exist
HINT: sudo modprobe kvm_intel
INFO: Your CPU supports KVM extensions

我正在寻找一个一行(理想情况下)来改变所有的实例:
# dropped packets chart for kvm890.0 = auto
至
dropped packets chart for kvm890.0 = no
我应该注意到"kvm890.0“是不同的,例如:
# dropped packets chart for kvm508.0 = auto
# dropped packets chart for kvm864.0 = auto
# dropped packets chart for kvm357.0 = auto
# dropped packets chart for
我正在尝试从FreeBSD 10.1-RELEASE (clang version 3.4.1)下的源代码构建top(1)。
# fetch http://www.unixtop.org/dist/top-3.7.tar.gz
# tar -xzf top-3.7.tar.gz
# cd top-3.7
# ./configure
# make
# make install
编译没有错误,但是编译的二进制文件不工作,给我的错误如下:
# top
kvm_open: kvm_nlist: No such file or directory
kvm_open: kvm_nlist: No such
我如何比较bash命令输出和使用IF ELSE块来做一些事情。
我尝试在CMD变量中捕获bash命令输出,如果变量为空/零,则输出缺少二进制/功能。非常基础。
在下面的代码中,第二个if else
# Check if the CPU supports KVM
cmd=$(grep -Eiw 'vmx|svm' /proc/cpuinfo)
if [[ $cmd -ne 0 ]];then
echo "CPU on this machine does not support KVM. Check documentation please"
fi
我正在尝试为Linux内核应用RT抢占补丁程序。正如这和这这样的指南所提到的,您应该这样做:
zcat patch-4.14.15-rt13.patch.gz | patch -p1
(假设您位于包含内核源代码的目录中。)
但我收到了很多信息,比如:
The next patch would create the file tools/testing/selftests/ftrace/test.d/trigger/inter-event/trigger-synthetic-event-createremove.tc,
which already exists! Assume -R? [n]
在我已经虚拟化的主机中,试图传递选项-enable-kvm -m 1024的选项将失败:
qemu-system-x86_64 -vga std -enable-kvm -m 1024 -monitor telnet:localhost:9313,server,nowait -drive file=my_img.img,cache=none
# Could not access KVM kernel module: No such file or directory
# failed to initialize KVM: No such file or directory
如果删除该选项
以前,我和熊猫一起吃蟒蛇0.18。使用下面的代码,我通过函数"calc_func“进行了计算,并将结果赋给DataFrame的列,即"A”和"B“。 df[["A", "B"]]=df.[["KV", "GV"]].apply(calc_func, axis=1) 在将pandas升级到0.24.1之后,此代码会生成一个索引,因为"None of [ KeyError (‘A’'B',dtype='object')] as in the column“ 我已经尝试了

我在Debian上运行MySQL (通常是从稳定包中安装)。
每次我下大订单时,mysql都会崩溃。示例查询(innodb表):
SELECT *
FROM `table`
INNER JOIN (
SELECT `key1`,
`key2`,
MAX(`date`) AS `date`
FROM `table`
WHERE `key2` = 1 # <-- Fancy variable to get different amount of datasets
AND `someOtherIndex` >= 5
我对android开发完全陌生。在安装了一个空项目的android studio并从AVD添加了一个像素设备之后。在运行时,它显示了错误
07/15 09:33:42: Launching 'app' on Pixel 3a API 28.
Error while waiting for device: Could not start AVD
我打开了AVD管理器,我可以看到
/dev/kvm device: permission denied
在故障排除选项中,我可以看到Grant current user access to /dev/kvm
我已经尝试了许多技巧,并且我
我正在Ubuntu VMWare虚拟机上运行Android。问题是,当我尝试使用AVD模拟器运行应用程序时,控制台中会出现以下错误:
